Abstract: Let $ G$ be a Lie group, and let $ \sigma $ be an involutive automorphism on $ G$. Then we establish a correspondence between unitary representations of $ G$ and unitary representations of a simply connected Lie group $ {G^*}$ dual to $ G$, where the duality is defined by the given involution $ \sigma $. The correspondence is obtained from a geometric assumption that was considered earlier in connection with reflection positivity. As a consequence of this construction, we obtain unitary representations of universal covering groups.
