报告题目：Progress on integrability of differential systems and its application

报告摘要：In this talk we report the progress on both algebraic integrability and local integrability of differential systems, and also their applications. On algegraic integrability we emphasis on Darboux theory of integrability and its relation with Liouvillian integrability. On local integrability, we concern the necessary and sufficient conditons of differential system in a neighborhood of a singular point.
