Compact Stein surfaces as branched covers with same branch sets
Abstract
For each integer , we construct a braided surface in and simple branched covers of branched along such that the covers have the same degrees and are mutually diffeomorphic, but Stein structures associated to the covers are mutually not homotopic. As a corollary, for each integer , we also construct a transverse link in the standard contact –sphere and simple branched covers of branched along such that the covers have the same degrees and are mutually diffeomorphic, but contact manifolds associated to the covers are mutually not contactomorphic.
