Short Proof of a Conjecture Concerning Split-By-Nilpotent Extensions
arXiv:1803.06794
Abstract
Let C be a finite dimensional algebra with B a split extension by a nilpotent bimodule E. We provide a short proof to a conjecture by Assem and Zacharia concerning properties of mod B inherited by mod C. We show if B is a tilted algebra, then C is a tilted algebra.
