Maxwell's equations
Speaker: Kshitij Sinha, IIT Bombay
Host: Harsha Hutridurga
Title: Time-Harmonic Maxwell's equations - Regularity theory and related topics
Time, day and date: 11:00:00 AM – 12:00:00 PM, Monday, February 02
Venue: Ramanujan Hall
Abstract: n this seminar, we will introduce a notion of weak solution for the time-harmonic Maxwell's equations. We will demonstarte that the associated weak formulation is well posed. Thereafter we will establish a regularity result proving Holder continuity of solutions.

Liquid Crystals
Speaker: Prof. Apala Majumdar, FRSE, FIMA, Department of Mathematics, University of Manchester, UK
Host: Parthanil Roy
Title: The Mathematics of Liquid Crystals - Theory and Applications
Time, day and date: 12:00:00 PM – 1:00:00 PM, Monday, February 02
Venue: Ramanujan Hall
Online: https://us06web.zoom.us/j/6950684207?pwd=VkNmYzFBd0c0QWx3azhJODJ0QUp1Zz09&omn=83584890072 (Meeting ID: 695 068 4207 Passcode: 802747)
Abstract: This mini-course will comprise four lectures on the mathematics of liquid crystals and modelling of liquid crystal applications. Liquid crystals are complex materials that combine fluidity with the ordering of solids and consequently, have fascinating physical, mechanical and rheological properties. Liquid crystals are best known as the working material of choice for the multi-billion dollar display industry. We will give a non-technical introduction to liquid crystals - their history, physics and applications, followed by an overview of the main mathematical theories for liquid crystals. We will conclude the lecture course with examples of mathematical modelling of real-life liquid crystal systems.

Number theory seminar
Speaker: Devadatta Hegde, School of Mathematics, TIFR, Mumbai
Host: Ravi Raghunathan
Title: Poles and Residues of Eisenstein Series:
Time, day and date: 4:00:00 PM - 5:00:00 PM, Monday, February 02
Venue: Ramanujan Hall
Abstract: Just as the Fourier transform involves the exponential function, the continuous spectrum of automorphic forms is expressed in terms of Eisenstein series. These series are meromorphic functions of one or several complex variables with values in the space of automorphic forms. Two fundamental questions concern the location of their poles and the contribution of their residues to the discrete spectrum. This talk presents our investigation into these problems.
