Abstract：
I will talk about large classes of dualities among 2d supersymmetric gauge theories obtained by compactifying 4d supersymmetric theories on S2 with a topological twist. These 2d theories include N=(0, 2), (2, 2)and (0, 4) supersymmetric theories. In this talk, I will present lots of open problems, puzzles, and future directions that I am currently exploring. This talk is based on joint works with Yiwen Pan [arXiv:2310.07965] and my students, Jiahao Zheng and Jiaqun Jiang [arXiv:2407.17350] + recent updates.
Bio：
I’m a mediocre researcher, and every day I find it incredibly difficult to make progress in research. I hope that someday, I’ll be able to write a paper with more ease.
