Frobenius splitting of Schubert varieties of semi-infinite flag manifolds

Syu Kato

We exhibit basic algebro-geometric results on the formal model of semi-infinite flag varieties and its Schubert varieties over an algebraically closed field $K$ of characte…

Loop structure on equivariant $K$ -theory of semi-infinite flag manifolds

Syu Kato

We explain that the Pontryagin product structure on the equivariant $K$ -group of an affine Grassmannian considered in [Lam-Schilling-Shimozono, Compos. Math. {\bf 146} (2010)] coin…

Nonsymmetric Rogers-Ramanujan sums and thick Demazure modules

Ivan Cherednik, Syu Kato

We consider expansions of products of theta-functions associated with arbitrary root systems in terms of nonsymmetric Macdonald polynomials at $t = \infty$ divided by their norms. Th…
