The Peterson comparison formula proved by Woodward relates the three-pointed Gromov-Witten invariants for the quantum cohomology of partial flag varieties to those for the complete flag. Another such comparison can be obtained by composing a combinat

We use k-Schur functions to get the minimal boundary of the k-bounded partition poset. This permits to describe the central random walks on affine Grassmannian elements of type A and yields a polynomial expression for their drift. We also recover Rie

We characterize the tempered part of the automorphic Langlands category $$\mathfrak {D}({\text {Bun}}_G)$$ D ( Bun G ) using the geometry of the big cell in the affine Grassmannian. We deduce that, for G non-abelian, tempered D-modules have no de Rha

Let X be a smooth, geometrically connected curve over a perfect field k. Given a connected, reductive group G, we prove that central extensions of G by the sheaf $${\mathbf {K}}_2$$ on the big Zariski site of X, studied in Brylinski–Deligne [5], ar

Let $$ {\overline{\mathrm{X}}}_{\uplambda} $$ be the closure of the I-orbit $$ {\overline{\mathrm{X}}}_{\uplambda} $$ in the affine Grassmanian Gr of a simple algebraic group G of adjoint type, where I is the Iwahori subgroup and λ is a coweight of

In their study of local models of Shimura varieties for totally ramified extensions, Pappas and Rapoport posed a conjecture about the reducedness of a certain subscheme of n × n {n\times n} matrices. We give a positive answer to their conjecture in

We introduce a notion of $$\xi $$ ξ -stability on the affine grassmannian $${\fancyscript{X}}$$ X for the classical groups, this is the local version of the $$\xi $$ ξ -stability on the moduli space of Higgs bundles on a curve introduced by Chaudou

The space of based loops in S L n ( C ) , also known as the affine Grassmannian of S L n ( C ) , admits an E 2 or fusion product. Work of Mitchell and Richter proves that this based loop space stably splits as an infinite wedge sum. We prove that the

Solving a singular linear system for an individual vector solution is an ill-posed problem with a condition number infinity. From an alternative perspective, however, the general solution of a singular system is of a bounded sensitivity as a unique e
