Constructor & Destructor Documentation

Hom (  const Source &    S, const Target &    T )  [inline]

Construct a homomorphism from a specific source ring S and target field T with Hom(S, T). The default behaviour is error. Specializations define all actual homomorphisms.

Member Function Documentation

Elt& image (  Elt &    t, const SrcElt &    s )  [inline]

image(t, s) implements the homomorphism, assigning the t the value of the image of s under the mapping. The default behaviour is a no-op.

SrcElt& preimage (  SrcElt &    s, const Elt &    t )  [inline]

If possible, preimage(s,t) assigns a value to s such that the image of s is t. Otherwise behaviour is unspecified. An error may be thrown, a conventional value may be set, or an arb value set. The default behaviour is a no-op.
