===== Weimin Chen (May 24 - May 31, 2022) =====

Professor of Mathematics\\
University of Massachusetts-Amherst

During his visit he will give two talks at GGTI, and the details of the talks are:

==== First Talk (May 26, 2022) ====

**Time:**10:00 AM IST\\
**Title:** Rational open books on Seifert manifolds.\\
**Abstract:** We will discuss how to construct rational open books on Seifert manifolds and to determine the contact structures supported by the open books. We will also discuss some potential applications. This is work in progress. 

==== Second Talk (May 27, 2022) ====

**Time:**14:30 AM IST\\
**Title:** Configuration of symplectic surfaces: a computational approach\\
**Abstract:** We will develop some computational techniques for the problem of existence and classification of configurations of symplectic surfaces in a rational surface. In this talk, we will discuss the general idea as well as how it is applied to some concrete problems. This is joint work in progress with Cagri Karakurt.
