| heal.abstract | Given a ring A, we form its truncated extensions A x (l)M. We study the extension groups Ext(A)(n) x (l)M(X,Y) in relation to Ext(A)(n)(X,Y), n is an element of N boolean OR {0}. If (A)M is flat, then using the theory of spectral sequences, we obtain a precise formula for Ext(A)(n) x (l)M(X,Y) for simple (A x (l)M)-modules. We also obtain bounds for gl.dim A x (l)M. In the case A is a semisimple ring, we prove the truth of the Strong No-Loops Conjecture for A x (l)M. (C) 1995 Academic Press, Inc. | en |
