Global dimensions of endomorphism algebras for generator-cogenerators   over $m$-replicated algebras
  Let $A$ be a hereditary artin algebra and $A^{(m)}$ be the $m$-replicated algebra of $A$. We investigate the possibilities for the global dimensions of the endomorphism algebras of generator-cogenerators over $A^{(m)}$.
