On elementary and geometric equivalence of equational co-domains
A. N. Shevlyakov Sobolev Institute of Mathematics, Pevtsova st. 13, Omsk, 644099 Russia
Abstract:
We prove that the class of equational co-domains is not closed under elementary and geometric equivalence. We find corresponding counter-examples in predicate and functional languages.
