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.
