Auslander-Reiten sequences and $t$-structures on the homotopy category of an abelian category

Erik Backelin, Omar Jaramillo

Published 2009-12-30, updated 2011-05-17Version 4

We use $t$-structures on the homotopy category $K^b(R-mod)$ for an artin algebra $R$ and Watts' representability theorem to give an existence proof for Auslander-Reiten sequences of $R$-modules.
