Title: Invariants and subgroups of some exceptional groups
Abstract of Talk
Given the Dynkin diagram of a simple Lie/algebraic group, one can list possible Lie subgroups, by looking at the list of all subgraphs of its (extended) Dynkin diagram using the famous Borel-De Siebenthal algorithm. Some of these may or may not exist over the ground field. In this talk, we shall discuss the situation for some exceptional groups and give a necessary condition for embeddings of simple groups in a given group over the ground field. This is a joint project with Ms. Neha Hooda.
