Abstract: General and diophantine definability in number rings and their polynomial rings are studied from a model-theoretic point of view. The main tool used is a modern form of the Theorem of Beth. For a ring R we consider the monoid EndR (R ) of all embeddings of a nonstandard enlargement R in itself which fix the standard elements. If R is a number ring or any field, the application of natural restriction ResR from End R[T ] (R[T ] ) to EndR (R ) is a well defined homomorphism of... (Update)
