On the holomorphic convexity of reductive Galois coverings over compact K\"ahler surfaces

Abstract

This article generalizes the result of Katzarkov and Ramachandran from algebraic surfaces to K\"ahler surfaces. We follow their argument to prove the holomorphic convexity of a reductive Galois covering over a compact K\"ahler surface which does not have two ends, except that we replace the $p$-adic factorization theorem by an analysis of the singularities of the continuous subanalytic plurisubharmonic exhaustion function.
