Abstract: Root System is a very important and beautiful object in mathematics, with the origin the classification of Lie groups and Lie algebras, and eventually plays an indispensable role in singularity theory. In this student seminar, we will first go through the basic concepts, including Weyl group, Cartan matrix, Dynkin Graph, etc, and give the classification of root systems. Then we will go into various related topics, namely, classification in Lie theory, Hermitian symmetric space, Mckay Correspondence, isolated singularities on complete intersections, etc.
