It is known that isomorphism implies elementary embeddability, and elementary embeddability implies elementary equivalence. Both converse statements are wrong. These three relationships in the class of models of some theory $T$ of a countable language $L$ of first order are considered.
Keywords: model theory, elementary embeddability, elementary equivalence.
Mots-clés : isomorphism
