Topological Type in Families of Germs.
Little is known about the global topology of the Fatou set U(f) for holomorphic endomorphisms , when k >1. Classical theory describes U(f) as the complement in of the support of a dynamically defined closed positive (1,1) current. Given any closed positive (1,1) current S on , we give a definition of linking number between closed loops in and the current S. It has the property that if lk(γ,S) ≠ 0, then γ represents a non-trivial homology element in . As an application, we use these linking...
A manifold is said to be Hessian if it admits a flat affine connection and a Riemannian metric such that where is a local function. We study cohomology for Hessian manifolds, and prove a duality theorem and vanishing theorems.
