18th Discussion Meeting in Harmonic Analysis

About Discussion Meeting in Harmonic Analysis(DMHA)

Discussion Meeting in Harmonic Analysis is a regular, biennial event organized by the Harmonic Analysts in India at various places. The first discussion meeting on 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 works, 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 a couple of themes, by experts in some of the promising fields. The DMHAs are intended to be accessible to mathematicians at the beginning of their career. In recent years, we have also started organizing a weeklong workshop just before the meeting.

The 18th discussion meeting in harmonic analysis will be held at the Department of Mathematics, Indian Institute of Technology Guwahati, from 18th to 21st December, 2023. (Due to the pandemic, the last DMHA, organized by NISER, Bhubaneswar was held online.) The meeting will be preceded by a workshop during the previous week, 11th to 16th December, 2023, in which we plan to have three/ four series of lectures in representation theory and harmonic analysis. As 2023 happened to be the birth centenary of the outstanding Mathematician Harish-Chandra, we have decided to celebrate the event with the upcoming DMHA. Consequently, the meeting is planned as a conference completely dedicated to Harish-Chandra where most of the lectures will be related to his works.


Harish-Chandra was a mathematician of great power, vision, and remarkable ingenuity. His profound contributions to the representation theory of Lie groups, harmonic analysis, and related areas left researchers a rich legacy that continues today. He was one of the outstanding mathematicians of his generation, an algebraist and analyst, and one of those responsible for transforming infinite-dimensional group representation theory from a modest topic on the periphery of mathematics and physics into a major field central to contemporary mathematics.

Harish-Chandra was born on 11th October 1923, in Kanpur, India. After receiving his master's degree in Physics, from the University of Allahabad in 1943, he moved to the Indian Institute of Science, Bangalore to work with Homi Bhabha. In 1945 he left India for the University of Cambridge where he worked with Paul Dirac. During his stay in Cambridge, he became increasingly interested in Mathematics. He obtained his Ph.D. in 1947 after which he went to the United States of America. After spending several years at Columbia University, in 1963 he moved to the Institute for Advanced Study in Princeton where he worked as the I.B.M.-von Neumann Professor of Mathematics until his sudden death on 16th October 1983.

Harish-Chandra received many awards in his career. He was a Fellow of the Royal Society of London, and a Fellow of the National Academy of Sciences. He won the Cole prize from the American Mathematical Society in 1954 for his papers on representations of semi simple Lie algebras and groups, and particularly for his paper. In 1974, he received the Srinivasa Ramanujan Medal from the Indian National Science Academy. In 2000 the erstwhile Mehta Research Institute (established in 1975) was renamed after Harish-Chandra.

IIT Guwahati

The event will be held on the sprawling campus of the Indian Institute of Technology Guwahati (IITG) which is situated on the banks of the majestic Brahmaputra River. The city of Guwahati is the gateway to North-East India. The Northeast states of India, with their rolling hills, green valleys and bubbling rivers, and mesmerizing aura, are popular with tourists across the globe. The states are also known for their cultural diversity and heritage. They are popular among tourists for their trekking routes, parks to spot wild animals in their natural habitat, ancient temples, and snow-covered mountain peaks. (click here for detail)
