WebLet I be a coherent subsheaf of a locally free sheaf O(E-0) and suppose that I = O(E-0)/I has pure codimension. Starting with a residue current R obtained from a locally free resolution of I we construct a. vector-valued Coleff-Herrera current it with support on the variety associated to I such that phi is in I if and only if mu phi = 0. Such a current mu can also be … Web15 Jul 2014 · The apparatus of sheaf theory has many applications wherever abstract homological methods are essential: in topology (homological and cohomological dimension, local homology and duality, the structure of various classes of continuous mappings, including imbeddings onto dense subsets, and, in particular, compactifications, etc.), in …

WebThe existence of universal unfoldings of certain germs of meromorphic connections is established. This is used to prove a general construction theorem for Frobenius manifolds. A particular case is Dubrovin’s theorem on semisimple Frobenius manifolds. Another special case starts with variations of Hodge structures. This case is used to compare two … speedy auto glass sudbury ontario

WebA sheaf of ideals Iis any subsheaf of O X. De nition 10.2. Let X = SpecA be an a ne scheme and let M be an A-module. M~ is the O X-module which assigns to every open subset U f the module M f. Remark 10.3. To realise (10.2) as a sheaf, note that M~(U) is the set of functions s: U ! a p2U M p; which can be locally represented at p as a=g, a 2M ... WebA subvariety in X is a set which locally is the set of points where a finite number of locally defined holomorphic functions vanish. The ideal-sheaf of a subvariety Y, denoted by Id Y, is the sheaf of germs of holo- morphic functions vanishing at every point of Y. http://fe.math.kobe-u.ac.jp/FE/FullPapers/49-1/49_133.pdf speedy auto glass sackville
