Definition df-imas 15122

Description: Define an image structure, which takes a structure and a function on the base set, and maps all the operations via the function. For this to work properly f must either be injective or satisfy the well-definedness condition f ( a ) = f ( c ) /\ f ( b ) = f ( d ) -> f ( a + b ) = f ( c + d ) for each relevant operation.

Note that although we call this an "image" by association to df-ima 4836, in order to keep the definition simple we consider only the case when the domain of F is equal to the base set of R. Other cases can be achieved by restricting F (with df-res 4835) and/or R ( with df-ress 14848) to their common domain. (Contributed by Mario Carneiro, 23-Feb-2015.)
