※ Zomm 병행: https://snu-ac-kr.zoom.us/j/2473239867  In 1960, Graham Higman introduced one of the fundamental conjecturesin finite group theory concerning the number of $p$-groups or order $p^n$. This is now known as Higman`s PORC conjecture. In this talk, I will give a brief survey on recent developments of thisconjecture. In particular, I will demonstrate how zeta functions,powerful classical tools from number theory, have become importantweapons to attack this problem.
