Başlık/Title: Standard group embeddings and divided differences operators.

Özet/Abstract: Briefly speaking, a standard group embedding is a normal projective compactification of a reductive group. They can all be obtained as certain projectivizations of reductive monoids. 
A complete combinatorial description of the equivariant cohomology of rationally smooth 
embeddings (a subclass that includes smooth and certain singular varieties), has been obtained in 
previous work by the author. An interesting open problem is to find an explicit set of polynomial 
generators for the various cohomology rings thus obtained. In this introductory talk, I will provide 
a survey of these topics and show how Newton's divided difference operators (and Schubert calculus) could be effectively used to solve the above-mentioned problem. This is joint work with K. Aker and Ö. Öztürk.
