The main focus of this series will be on the research directions that explores applications of Combinatorics in Algebra, Topology and Graph Theory (CATGT). Some of the possible directions are Topological Combinatorics, Combinatorial Commutative Algebra, Combinatorial properties of graphs, etc. This will be a great opportunity for graduate students and young researchers to get to know each other and learn more about the ongoing research in these areas.
The talks will typically take place on each Wednesday at 11:00 AM IST (UTC+05:30). The webinar is hosted on Zoom. If you are interested in giving a talk or would like to get email notification for upcoming talks, please fill the form here.
We especially encourage graduate students and early career researchers to come forward and present their research in the aforementioned topics. Enthusiastic undergraduate and masters students are also welcome to give talks in this series. Expository talks are equally welcome.
Recording of past webinars are available on our YouTube channel. Feel free to write back to us at seminarCATGT@gmail.com, in case of any query.
We are thankful to Chennai Mathematical Institute for providing us with a Zoom account for conducting these webinars.
