A Polar Decomposition for Holomorphic Functions on a Strip

WebFunctions in Hardy spaces on multiply-connected domains in the plane are given an explicit characterization in terms of a boundary condition inspired by the two-dimensional Ising model. The key underlying property is the positivity of a certain operator constructed inductively on the number of components of the boundary. WebLet f : !C be a holomorphic function. Let U be the subset of consisting of points aso that f0(a) 6= 0 :Then Uis open and f: U!C is locally univalent. Theorem 1.2. Let Ube an open set of C and fbe a univalent function on U:Then f06= 0 on Uand f: U!f(U) is biholomorphic.

Web25 feb. 2024 · 1 Answer. The answer is no. It is enough to look at the plot drawn with Maple. Yes, if the function has some singularities on the boundary then it can not be extended even continuously. I should have put some more assumptions. Thank you for the nice maple plot. @LUX: Consider g ( z) := e − 1 1 − z.
