Algebra Seminar: Yakimova -- Symmetric invariants and polynomial rings

Oksana Yakimova (Friedrich-Schiller-University Jena) 

Friday 3 March, 12-1pm, Place: Carslaw 175 

Title: Symmetric invariants and polynomial rings.  

Abstract: For a reductive Lie algebra g of rank r, the ring of symmetric invariants
S(g)^g is a polynomial ring in r variables.  We will discuss the importance of this
property and then describe some other (non-reductive) Lie algebras having it.
