On the syntactic characterization of some model theoretic relations

In this thesis we consider binary relations over the class of L-structures, for some fixed language L. Such a binary relation R, induces a binary relation R* between the class of theories in L; in the following natural way. If T1 and T2 are theories in L then T1R*T2 if ∃A,B A T1 , Bf T2 an...
