Title: Reductive Group Actions on Affine and Local Rings
Abstract: In the first part of the talk we will review some basic results about reductive groups, their actions on affine varieties, rings of invariants, etc. In the second part I will mention many results I have proved in this area. In the last part I will state some results about reductive group actions on local analytic rings. Making use of these recent proofs of two conjectures I had made in 1990 will be mentioned.
