Harish Chandra Lecture Series :
1. First Lecture of the Series:
First Lecture was delivered by Prof. Mahan Mj on January 28th, 2019.
Topic: "What is hyperbolic geometry? "
Abstract: We shall indicate a solution to a problem posed by Euclid: Prove or disprove the parallel postulate assuming only the first 4 axioms of Euclidean geometry. The solution leads to a new geometry called hyperbolic geometry. We shall only assume some familiarity with calculus.
About the Speaker: Mahan Mj is an Indian mathematician and monk of the Ramakrishna Order. He is currently Professor of Mathematics at the Tata Institute of Fundamental Research in Mumbai. He is best known for his work in hyperbolic geometry, geometric group theory, lowdimensional topology and complex geometry. He is a recipient of the 2011 Shanti Swarup Bhatnagar Award in Mathematical Sciences and the Infosys Prize for Mathematical Sciences in 2015. He was an invited speaker at the International Congress of Mathematicians in 2018 in the geometry section.
Mahan Mj studied at St. Xavier's Collegiate School, Calcutta, till Class XII. He then entered the Indian Institute of Technology Kanpur, with AIR 67 in the Joint Entrance Examination, where he initially chose to study Electrical Engineering but later switched to Mathematics. He graduated with a Masters in Mathematics from IIT Kanpur in 1992. Mahan Mitra joined the PhD program in mathematics at the University of California, Berkeley, with Andrew Casson as his advisor.
2. Second Lecture of the Series:
Lecture Series on "Weak Solutions, Stability and Stabilizability of PDE" Speaker: Prof. Mythily Ramaswamy (TIFR CAM Bangalore) Date: 6th to 10th May 2019 (Except on Wednesday 8th May) Time: 04:00 P.M. 

Abstract of the talk: The concepts of Stability and stabilizability for ODEs will be introduced and then Linear Regulator problem and feedback stabilization will be touched upon. For timedependent PDEs, existence using semigroup theory will be outlined. Stability and stabilizability for such PDEs will be discussed. 

About the Speaker: Mythily Ramaswamy is an Indian mathematician and professor in the Department of Mathematics at the Tata Institute of Fundamental Research Centre for Applied Mathematics in Bangalore. Her research involves Functional Analysis and Controllability of Partial Differential Equations. She obtained her doctorate in 1990 from Pierre and Marie Curie University in Paris under the supervision of Henri Berestycki. Ramaswamy was the 2004 winner of the Kalpana Chawla Award of the Karnataka State Council for Science and Technology, "given to a young woman scientist for achievements in the field of science and technology“. She was elected to the Indian Academy of Sciences in 2007. She became a Fulbright Scholar for 2016–2017, funding her to visit Michael Renardy at Virginia Tech.
