Title: Some algebraic geometry – II
Abstract:  This is the second lecture on this topic. We are following the first chapter of Tony A. Springer's book. In this lecture, we will discuss locally ringed spaces and then give the definition of an affine algebraic variety.

Seminar on stochastic processes

Host: Ayan Bhattacharya

Speaker: Siva Athreya, ICTS, Bengaluru

Title: Graphon-valued Stochastic Processes

Abstract: We will present our attempts thus far to develop a theory of 
graphon-valued stochastic processes. We will present a brief review of 
the theory of Graphons and dynamics constructed on the space of 
graphons. We shall construct and analyze a natural class of such 
processes arising from population genetics. In conclusion, we shall 
present the challenges in our ongoing work on constructing dynamics 
where the edges and vertices interact with each other. This is joint 
work with Frank den Hollander and Adrian Roellin.
