Abstract
We prove a decomposition theorem for wild division algebras over a Laurent series field with arbitrary residue field of characteristik greater than two. This theorem is a generalization of the decomposition theorems for tame division algebras given by Jacob and Wadsworth. Also we prove a generalization of Cohen's theorem.
