Compactly supported cohomology of buildings
Suppose (W,S) is a Coxeter system. A subset T ⊂ S is spherical if it generates a finite subgroup of W . S denotes the poset of spherical subsets of S. Let Φ be a building in the sense of [6] (i.e., Φ is a set of chambers, equipped with a family of adjacency relations indexed by S and a W -valued distance function, Φ×Φ→W ). Let A denote the set of finitely supported Z-valued functions on Φ (i.e....
متن کاملThe Penrose transform for compactly supported cohomology
Let the manifold X parametrise a family of compact complex submanifolds of the complex (or CR) manifold Z. Under mild conditions the Penrose transform typically provides isomorphisms between a cohomology group of a holomorphic vector bundle V → Z and the kernel of a differential operator between sections of vector bundles over X. When the spaces in question are homogeneous for a group G the Pen...
متن کاملCompactly Supported Shearlets
Shearlet theory has become a central tool in analyzing and representing 2D data with anisotropic features. Shearlet systems are systems of functions generated by one single generator with parabolic scaling, shearing, and translation operators applied to it, in much the same way wavelet systems are dyadic scalings and translations of a single function, but including a precise control of directio...
متن کاملCompactly Supported Distributions 803
In this note, we present results on the representation of any compactly supported distribution by a nite linear combination of linearly independent integer translates of distributions. As an application we obtain a self-adaptive stability lemma.
متن کاملA finiteness result for the compactly supported cohomology of rigid analytic varieties, II
— Let h : X → Y be a separated morphism of adic spaces of finite type over a non-archimedean field k with Y affinoid and of dimension 6 1, let L be a locally closed constructible subset of X and let g : (X, L)→ Y be the morphism of pseudo-adic spaces induced by h. Let A be a noetherian torsion ring with torsion prime to the characteristic of the residue field of the valuation ring of k and let ...
