I'm trying to prove that propositional logic is sound and complete, using the notion of morphism between consequence systems, i.e., pairs $langle C,vdashrangle$ where C is a signature and $vdash:wp L(C)rightarrow wp L(C)$ is a map between the language generated by the signature.



More specifically, I'm trying to find a morphism



$h:langle C,vdashranglerightarrowlangle C,vDashrangle$



which by definition would imply that



$h(Gamma^vdash)subseteq(h(Gamma))^vDash$



Is this possible? And if so, what morphism could I use?
