## Abstract Aiming at establishing a firm basic theory to ring‐based information network management systems, our paper proposes a tie‐set graph theory. We define a binary vector representing a tie‐set in a biconnected undirected graph __G__=(__V__,__E__) as a tie‐set vector. The set of tie‐set vect

Given two graphs G=(X,E), H=(Y,F); If AcX and if f is a function from A to Y, we pose the problem of deciding if f can be extended into a homomorphism from G to H. We know how to solve this problem when H is, for instance, a tree, or a chordal graph. We give here a solution to this problem when g is
