Affine flag manifolds are limitless dimensional types of regular items comparable to Gra?mann kinds. The publication gains lecture notes, survey articles, and learn notes - according to workshops held in Berlin, Essen, and Madrid - explaining the importance of those and similar gadgets (such as double affine Hecke algebras and affine Springer fibers) in illustration thought (e.g., the speculation of symmetric polynomials), mathematics geometry (e.g., the elemental lemma within the Langlands program), and algebraic geometry (e.g., affine flag manifolds as parameter areas for significant bundles). Novel points of the speculation of vital bundles on algebraic kinds also are studied within the booklet.

Let γ be an integral equivalued regular element of (Lie T )(L), where T ⊂ GL is a maximal torus. Then the affine Springer fiber F (γ) has pure cohomology. 10. V. Lucarelli [56] has provided examples of affine Springer fibers for PGL3 and elements of unequal valuation which admit pavings by affine spaces, thus proving the purity conjecture in these cases. 8. The fundamental lemma The fundamental lemma, sometimes called, more appropriately, the matching conjecture of Langlands and Shelstad, is a family of combinatorial identities which relate orbital integrals (of different sorts) for different groups, which was conjectured by Langlands and Shelstad [50].

We define maps from the extended affine Weyl group W to the finite Weyl group W as follows: η1 : W = X∗ (T ) W → W, the projection η2 : W → W, where η2 (x) is the unique element v ∈ W such that v−1 x ∈ S W η(x) = η2 (x)−1 η1 (x)η2 (x). 36 U. G¨ortz Let x ∈ W , and let b be a representative of the unique basic σ-conjugacy class corresponding to the connected component of x. We define the virtual dimension (of Xx (b)): 1 (x) + (η(x)) − def(b) . d(x) = 2 The following conjecture which extends a conjecture made by D.
