Anote on elimination of imaginaries for pairs of fields


Abstract


We show that, if B is a field and A \neq B is any algebraically closed  field extension of B, then the theory of (A,B) eliminates imaginaries if  and only if A is a finite extension of B (and so if and only if (A,B)  is elementary equivalent to ( \mathbb{C}, \mathbb{R})).
