Professor of Mathematics\\
University of Massachusetts-Amherst

Weimin Chen, ziyareti süresince GGTE'de iki konuşma verecektir. Detaylarını aşağıda bulabileceğiniz konuşmalara ilgili herkes davetlidir. Konuşmalar yüz yüze yapılacak olup konuşma dili İngilizce olacaktır. 

==== First Talk (26 Mayıs, 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:**10:00 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.
