Abstract
In this paper we characterize the h-vector of a Gorenstein codimension three domain. Main tool is a lifting theorem which asserts that every codimension three homogeneous Gorenstein ideal with degree matrix verifying certain numerical conditions can be lifted to a codimension three Gorenstein prime ideal.
