Examples of VH-spaces include, but is not limited to, the chain of locally Hilbert $C^*$-modules, Hilbert $C^*$-modules and Hilbert Spaces.<br><br>In this talk, after a brief discussion of VH-Spaces with examples and basic properties, 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. If time permits, we discuss an application of this result as well.</span><u></u><u></u></p></div></div>_______________________________________________<br>
