AbstractWe introduce certain class of quadratic algebras together with commutative subalgebras generated by additive and multiplicative Dunkl elements correspondingly. We identify these subalgebras with cohomology and K-theories of type A flag varieties. We show that value of Schubert polynomials on additive Dunkl elements is a generating function for the corresponding Littlewood-Richardson coe...
AbstractIn the first lecture I will give an introduction to toric algebras. toric algebra can be seen as a monomial subalgebra, or as a quotient of apolynomial ring by a binomialprime ideal. We will discuss how to move between these two presentations, and compute the Krull dimension of a torialgebra. The monomial preentation provides a link betwen combinatorial obiects and algebraic structures....
