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 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.</p><p>--------------------------------------------------------------------</p><div><div style="color:rgb(0,0,0)"><div style="margin:0px;padding:0px 0px 20px;width:568px;color:rgb(34,34,34);font-family:Roboto,RobotoDraft,Helvetica,Arial,sans-serif;font-size:medium"><div><div id="gmail-m_-3724630280005366880gmail-m_-1061050150423670915gmail-m_1885184350414612377gmail-m_-555535382709098613gmail-m_5974778985745939799gmail-m_-6178667071958242608gmail-:nr" style="font-size:0.875rem;direction:ltr;margin:8px 0px 0px;padding:0px"><div id="gmail-m_-3724630280005366880gmail-m_-1061050150423670915gmail-m_1885184350414612377gmail-m_-555535382709098613gmail-m_5974778985745939799gmail-m_-6178667071958242608gmail-:ns" style="overflow:hidden;font-variant-numeric:normal;font-variant-east-asian:normal;font-stretch:normal;font-size:small;line-height:1.5;font-family:Arial,Helvetica,sans-serif"><div dir="ltr"><div><div><div style="color:rgb(0,0,0)">.</div><div></div><div style="color:rgb(0,0,0)"><br></div></div><div>İyi günler dileğiyle,</div><div><br></div><div>Temha<div class="gmail-yj6qo"></div><div class="gmail-adL"></div><div class="gmail-adL"></div><div class="gmail-adL"></div><div class="gmail-adL"></div><div class="gmail-adL"><br></div></div></div></div></div></div></div></div></div></div></div><div class="gmail-yj6qo"></div><div class="gmail-adL"><div style="color:rgb(0,0,0)"><div style="margin:0px;padding:0px 0px 20px;width:568px;color:rgb(34,34,34);font-family:Roboto,RobotoDraft,Helvetica,Arial,sans-serif;font-size:medium"><div id="gmail-m_-8206525956552967813gmail-m_7174835793193528702gmail-m_-3730883342606971862gmail-m_5974778985745939799gmail-m_-6178667071958242608gmail-:nr" style="font-size:0.875rem;direction:ltr;margin:8px 0px 0px;padding:0px"><div id="gmail-m_-8206525956552967813gmail-m_7174835793193528702gmail-m_-3730883342606971862gmail-m_5974778985745939799gmail-m_-6178667071958242608gmail-:ns" style="overflow:hidden;font-variant-numeric:normal;font-variant-east-asian:normal;font-stretch:normal;font-size:small;line-height:1.5;font-family:Arial,Helvetica,sans-serif"><div dir="ltr"><div><div></div><div></div><div></div><div><br></div></div></div></div></div></div></div></div></div>
