INDIAN WOMEN AND MATHEMATICS (IWM) Annual Conference , July 13-15, 2023

Indian Women and Mathematics (IWM) is a collective of mathematicians that has been in existence since 2009. Its objectives over the years have been to encourage more women to pursue higher education in mathematics, and to provide an environment, and exposure to new trends, that enables them to take up careers in mathematics. To effectively serve its objectives, IWM organizes various activities throughout the year in different parts of the country. The activities of IWM are funded by the National Board for Higher Mathematics (NBHM), Department of Atomic Energy (DAE), Govt. of India and are supported by the Committee for Women in Mathematics (CWM), International Mathematical Union (IMU). In association with IISER Bhopal, IWM is organizing an Annual Conference during July 13-15, 2023. The IWM Annual Conference aims to bring together women students, college and university teachers and early-career researchers working at the frontiers of mathematics to exchange mathematical ideas and share their experiences. A major goal of this event is to enable junior women mathematicians to interact with their senior colleagues, both individually and in small groups. In addition to the invited talks, there will be contributory talks and poster sessions that will facilitate interactions of young researchers with senior mathematicians. Venue of the conference: IISER Bhopal

Symposium , March 03 - 04, 2023

The IISER Bhopal Math Symposium of the Department of Mathematics was conceived as a platform for Ph.D. students and postdoctoral researchers to present their research and to engage in fruitful discussion amongst them and faculty members with disparate research interests. The first Math symposium was held in February 2018 and has been held every year since then. While the past two editions of the event were conducted in hybrid mode due to the nationwide lockdown, this year, we plan to hold it in offline mode as an in-house activity. The Math symposium 2023 will have two plenary talks by invited speakers along with contributed talks in Algebra, Analysis, and Geometry-Topology by the Ph.D. students and the postdoctoral fellows of the department.

Symposium , March 25-26, 2022

The IISER Bhopal Math Symposium of the Department of Mathematics was conceived as a platform for postdoctoral researchers and Ph.D. students to present their research and to engender fruitful discussion amongst them and faculty members with disparate research interests. The first symposium was held in February 2018 and has been held every year since then. While the first two editions were in-house events, starting in 2020, the theme of the symposium has been broadened by including 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. Keeping the theme intact, the fifth installment of the IISER Bhopal Math Symposium this year will have two plenary talks followed by 14-15 talks each in Algebra, Analysis, and Geometry-Topology.

Symposium , March 25-26, 2021

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).

16th Discussion Meeting in Harmonic Analysis, 16-19 Dec 2019

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.

NCM Workshop in Harmonic Analysis, 10-14 Dec 2019

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).


NCMW - Operator Algebras, Quantum Groups and Noncommutative Geometry, July 1-13, 2019

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.

NCM workshop on Contact and Symplectic Geometry, December 3-14, 2018

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.
