Abstract
Quantum symmetry in simple graphs is a well-explored topic within noncommutative mathematics. It has also gained increasing significance in quantum information theory in recent years. In this talk, we will introduce various notions of quantum symmetry in finite multigraphs in the category of compact quantum groups, naturally extending the well-known constructions done by Banica and Bichon in the context of simple graphs. Towards the end of the talk, we will discuss some examples and applications of our constructions.

Speaker Intro
Asfak completed his Ph.D. under the supervision of Professor Debashish Goswami at the Indian Statistical Institute, Kolkata, on December 1, 2023. His research primarily focuses on quantum symmetries of finite spaces and their applications across various areas of mathematics and physics. He is also exploring other areas of noncommutative mathematics as well. Currently, he is a postdoctoral fellow at the Indian Institute of Science Education and Research (IISER), Bhopal. The talk he will be presenting at the BIMSA-Tsinghua Quantum Symmetry Seminar is based on his doctoral research.
