The In-House Symposium of the Department of Mathematics was conceived as a platform for postdoctoral researchers and PhD students to present their research, and to engender fruitful discussion amongst them and faculty members with disparate research interests. The last two years the symposium was successful in its objectives. In its fourth edition this year, we have two plenary talks followed by 14-15 talks in each section (namely Algebra, Analysis and Geometry-Topology).

Please see the schedule for the details. 1st Day Schedule | 2nd Day Schedule

The Indian Institute of Science Education and Research, Bhopal (IISERB) is pleased to host ISLA 2020, the 8th Indian School on Logic and its Applications. The school will be held from 4th to 9th May, 2020 and include intensive sessions on logic and its various applications by reputed scholars in the field. The school welcomes students from all over the country and from diverse fields of study, including Mathematics, Philosophy, Computer Science, Linguistics, and other related areas. ISLA 2020 will focus on training in First-Order Logic, Set Theory, Model Theory, and Philosophy of Mathematics.

The In-House Symposium of the Department of Mathematics was conceived as a platform for postdoctoral researchers and PhD students to present their research, and to engender fruitful discussion amongst them and faculty members with disparate research interests. The first symposium was held on February 03, 2018, and Prof. V. Srinivas (TIFR Mumbai) was present as an external guest. In addition to his plenary talk, there were six other talks; three by post-docs and three by PhD students. The second symposium was held on 8th and 9th of February, 2019. Dr. Manjunath Krishnapur from IISc Bangalore was invited as the special guest. In addition to his excellent plenary talk, there were eleven other talks — five by postdocs and six by PhD students. The Symposium also included a poster presentation by some PhD students. This year, we have broadened the theme of the Symposium to include more invited talks by researchers from Institutes across the country. We believe this would motivate and guide our students in their research endeavors and also provide an atmosphere for collaborative research across disciplines.

The first discussion meeting in harmonic analysis (DMHA) was organized by Professor M. G. Nadkarni at the University of Bombay in 1988. It had a very small budget and around 25 participants. The meeting was a great success and the participants decided to have a meeting once every two years at different locations across the country. The vision of that initial group was to have a meeting of all practitioners and students of harmonic analysis in the country, where they would be able to present their work, and discuss new developments in the subject. As participation in the biennial meeting has grown over the years, their vision has been realized. The core of a DMHA is a series of lectures focusing on one theme, by an expert in one of the promising fields. The DMHAs are intended to be accessible to mathematicians at the beginning of their career.

**Speaker:** Luca Fanelli (SAPIENZA Università di Roma, Italy)

**Description:** First set of lectures will be on **Uniform Resolvent Estimates for Laplace and Dirac operators and applications**. The plan of these lectures is as follows:

**i)** Introduction, non self-adjoint Hamiltonians and eigenvalue problems. The Birman-Schwinger Principle and absence of eigenvalues, as a consequence of uniform resolvent estimates for the free Hamiltonian. An overview of recent results in the non-relativistic case (Frank, Seiringer, Simon et al).

**ii)** The uniform Sobolev Estimate for the resolvent of the free Schrödinger Hamiltonian by Kenig-Ruiz-Sogge. Proof, and failure of the estimate for the Dirac Hamiltonian.

**iii)** A new Agmon-Hörmander-type estimate for the free Dirac operators. As a consequence, absence of eigenvalues for Dirac operators with almost scaling invariant complex potentials. The results are obtained in collaboration with P. D’Ancona, and N. Schiavone (Roma Sapienza).

In this workshop, we studied three fundamental areas of Operator Algebras, each of which is an important and involved field in its own right: (i) Noncommutative Geometry [taught by Dr. Sayan Chakraborty (IISER, Bhopal) and Prof. Arup K. Pal (ISI, Delhi)], (ii) K-theory [taught by Dr. Rohit Holkar (IISER Bhopal), and Dr. Prahlad Vaidyanathan (IISER Bhopal)], and (iii) Quantum Groups [taught by Dr. Sutanu Roy (NISER, Bhubaneshwar)]. Each course consisted of some introductory lectures in the first week, while the second week consisted of more advanced material, reflecting modern research trends within the subject. The students attending the workshop were either in an advanced stage of their PhD program, or post-docs working in related fields. The feedback from the students and the faculty was overwhelmingly positive, and the workshop was a great success.

The National Conference on Commutative Algebra and Algebraic Geometry (CAAG) was held at IISER Bhopal during July 2-6, 2019. This is a part of biennial national / international conference on Commutative Algebra and Algebraic Geometry being held over the last two decades. Around sixty people participated in the conference. The conference brought together senior and young researchers for exchange of ideas. It also provided a platform for the young researchers to be updated on the latest developments in the subject.

The In-House Symposium of the Department of Mathematics was conceived as a platform for post-doctoral researchers and PhD students to present their research, and to engender fruitful discussion among them and faculty members with disparate research interests. The second symposium was held on 8th and 9th of February, 2019. Dr. Manjunath Krishnapur (IISc) was invited as a special guest. In addition to his excellent plenary talk, there were eleven other talks; five by post-docs and six by PhD students, and several lively discussions over coffee. The Symposium also included a poster presentation by some PhD students. The culture of free exchange of ideas that has been a core value of the department was there for all to see, and it is hoped that future iterations continue building on this.

In the last two decades, the area of Contact and Symplectic Geometry has been growing very rapidly. The geometry and topology of Contact and Symplectic structures is intimately tied with the properties of the manifolds on which these structures rest. This area has interesting and intriguing connections with many fields in mathematics and physics.

In this workshop, we wish to give the audience a fairly good knowledge about the two dominant features of Contact and Symplectic structures, namely "Flexibility" and "Rigidity" as envisaged by Gromov and propagated further by Eliashberg and others.

The flexibility refers to a feature of these structures where “h-principle” type results can be proved while the rigidity refers to an aspect that relies on the use of “J-holomorphic curves”. The fine line that differentiates the flexibility and the rigidity has been elusive, and is a matter of great mathematical interest.

The first week of the workshop will recall briefly the basics of Contact and Symplectic Geometry. The connections with other fields of mathematics and physics will be discussed. Eliashberg's classification of overtwisted contact structures in dimension three will also be discussed. There will be talks on the introduction to J-holomorphic curves.

The second week will consist of lectures on advanced topics that reflect the current research trends in Contact and Symplectic Geometry. The students in the advanced stages of PhD program, postdocs and young faculty members working in this or related fields will greatly benefit from this workshop.

Basic knowledge in algebra, analysis and topology forms the core of all Advanced Instructional Schools organized by NCM. The main objectives of AFS are to bring up students with diverse background to a common level and help them acquire basic knowledge in these subjects required in Advanced Instructional Schools.

AFS programs are targeted at fresh Ph. D. students in research institutions and universities in the country.

The SMMC is an international mathematics competition involving participation from students from various institutions from the Asia Pacific region.

The first In-House Symposium of the Department of Mathematics was conceived as a platform for post-doctoral researchers and PhD students to present their research, and to engender fruitful discussion amongst them and faculty members with disparate research interests. The Symposium was held on February 03, 2018, and Prof. V. Srinivas (TIFR Mumbai) was present as an external guest. In addition to his plenary talk, there were six other talks; three by post-docs and three by PhD students. The Symposium ended with a poster presentation by some PhD students, along with lively discussions. The culture of free exchange of ideas that has been a core value of the department was there for all to see, and it is hoped that future iterations continue building on this.

The purpose of this two-day workshop is to provide an opportunity to young teachers, researchers and students of Mathematics to learn about important topics in Geometry, Topology and their applications from active researchers and experts.

A two days lecture workshop on “Geometry and Topology” was held on 20th & 21th Jan 2018 at IISER Bhopal, Madhya Pradesh. The workshop was organized by Department of Mathematics, in association with Indian National Science Academy, New Delhi, The National Academy of Sciences, Allahabad and Indian Academy of Sciences, Bangalore.

Prof. (Dr.) A. J. Parameswaran, School of Mathematics, Tata Institute of Fundamental research was the workshop Convener and Dr. Sanjay Kumar Singh, Assistant Professor, Department of Mathematics, Indian Institute of Science Education and Research was the Coordinator. Fellows from Science Academies’ and eminent academicians from reputed institutions were invited in the workshop to disseminate the proposed concepts to the participants.

The lectures in this workshop have covered specific topics which were relevant to the teachers' classroom instructions. An important component of this program was the discussion hour during which the participants interacted with each other and cleared their doubts and worked-out routine into advanced exercises. In this workshop, participant learned the basics of mathematics and use them to study some specific topics in Geometry and Topology. Through these topics, Speakers has discussed some questions of current interests to get a flavor of ongoing research in these areas.

The main intention to organize this workshop was to promote mathematics in Bhopal and improve quality of teaching which is essential for motivating students for research in Mathematics. We hope that after attending this school, our participants would be able to motivate and encourage their students to study Mathematics at the higher level.
