Web25. jún 2024 · Perverse schobers are categorifications of perverse sheaves. In prior work we constructed a perverse schober on a partial compactification of the stringy Kähler moduli space (SKMS) associated by Halpern-Leistner and Sam to a quasi-symmetric representation of a reductive group. ... For further reference we recall the following results ... WebThe mathematical term perverse sheaves refers to a certain abelian category associated to a topological space X, which may be a real or complex manifold, or a more general topologically stratified space, usually singular. This concept was introduced in the thesis of Zoghman Mebkhout, gaining more popularity after the work of Joseph Bernstein, … WebIn § § \lx@sectionsign § 1.4, we state the decomposition theorem in terms of intersection cohomology without any reference to perverse sheaves. The known proofs, however, use in an essential way the theory of perverse sheaves which, in turn, is deeply rooted in the formalism of sheaves and derived categories. grove narberth pembrokeshire
