报告摘要：

Since Mumford's GIT in 60s, people tried to generalise the theory for general groups. A special type of non-reductive group called graded unipotent group attracted attention. A recent application was Berczi and Kirwan's compatification of moduli of k-jets and a new lower bound for hyperbolicity. I will introduce their methods in constructing quotients for graded unipotent group actions.
