We present a new deterministic algorithm for constructing homomorphism spaces and endomorphism rings of finite-dimensional modules. The modules are given via vertex projective presentations over path algebras and finite-dimensional quotients of path algebras. We use the theory of right GrΓΆbner bases
This paper gives the following description of K of the endomorphism ring of a 0 finitely generated projective module. THEOREM. Let T be a ring and P a finitely generated, projecti¨e T-module. Let I Ž . Ž . be the trace ideal of P. Then K End P is isomorphic to a subgroup of K T, I . If, n phic to
