The 19^th Discussion Meeting in Harmonic analysis (DMHA) will be held at IISER Mohali from 16-19 December, 2025. DMHA is an international conference in harmonic analysis conducted once in every two years by the harmonic analysis community of India. The first discussion meeting on harmonic analysis (DMHA) was organised by Professor M. G. Nadkarni at the University of Bombay in 1988. For details of the past events and further history see this link.

There will also be a workshop on Harmonic analysis and Operator theory (HAOT) the week before DMHA featuring mini courses in various topics in harmonic analysis and operator theory.

UPDATES:

1. Registration for the workshop HAOT is closed now.

2. Registration link for DMHA is closed now.

Selected participants have been informed for both the above events.
