The Ceresa cycle and the Gross—Kudla—Schoen modified diagonal cycle are algebraic 1cycles associated to a smooth algebraic curve. They are algebraically trivial for a hyperelliptic curve and nontrivial for a very general complex curve of genus >2. Given an algebraic curve, it is an interesting question to study whether the Ceresa and GKS cycles associated to it are rationally or algebraically trivial. In this talk, I will discuss some methods and tools to study this problem.
