Depth for complexes and intersection theorem

WebAug 28, 2007 · The intersection theory of tautological classes on the moduli space of curves is a very important subject and has close connections to string theory, quantum gravity and many branches of mathematics. The n -Point Functions for Intersection Numbers Definition 1: We call the following generating function the n-point function. WebWe present an obstruction theoretic inductive construction of intersection space pairs, which generalizes Banagl's construction of intersection spaces for arbitraty depth stratifications. We construct intersection space pairs for pseudomanifolds with compatible trivial structures at the link fibrations; this includes the case of toric varieties.

WebThe subcomplex of the de Rham complex Ω∗(E,∇) defined in Lemma 2.1 is called the intersection complex of (E,∇) and denoted by Ω∗ int(E,∇). The λ = 1 case is called an intersection de Rham complex and the λ = 0 case is called an intersection Higgs complex. These two types of intersection complexes are our principal objects of study.
