split monomorphism造句

A "'split monomorphism "'is an homomorphism that has a right inverse.
That is, an homomorphisms f \ colon A \ to B is a split homomorphism if there exists an homomorphism g \ colon B \ to A such that g \ circ f = \ operatorname { Id } _ A . A split monomorphism is always a monomorphism, for both meanings of " monomorphism ".
Here we use the usual notation A ^ n = A \ times \ ldots \ times A ( n times ) as well as the common notion, p is a split epimorphism if there is a homomorphism q in the reverse direction such that pq = identity on the image of p . ( Sometimes the subring B in A is referred to as the ring extension A over B; the theory works as well for a ring homomorphism B into A, which induces right and left B-modules structures on A . ) Equivalently, the condition for left or right depth two may be given in terms of a split monomorphism of bimodules where the domains and codomains above are reversed.
