Mudumbai Seshachalu Narasimhan, Indian mathematician (Thandarai, Tamil Nadu State 07 June 1932 – 16 May 2021)

Pioneer of the study of moduli spaces of holomorphic vector bundles on projective varieties

Proved Narasimhan-Seshadri theorem (1965)

With G. Harder introduced canonical filtrations on algebraic vector bundles 

With S. Ramanan proved the existence of universal connections in differential geometry (1961-3) and introduced the notion of Hecke correspondence between moduli spaces of vector bundles

With Nori proved that there are only finitely many smooth projective curves having a given abelian variety

With Simha showed the existence of a global moduli space
