A $VH$-space (Vector Hilbert Space in the sense of Loynes) is a complex complete locally convex space with a suitable ordered vector space valued inner product. Examples of $VH$-spaces include, but is not limited to, the chain of locally Hilbert $C^*$-modules, Hilbert $C^*$-modules and Hilbert Spaces.

In this talk, after a discussion of $VH$-Spaces with basic properties and some examples, we state a general dilation theorem for positive semidefinite kernels valued in adjointable operators on a barrelled $VH$-space. We prove that, under barrelledness assumption, a necessary and sufficient condition for the existence of a natural $VH$-space dilation, or equivalently, a reproducing kernel $VH$-space representation of the kernel, is satisfied automatically.
