On algebras of ${\Omega }^n$-finite and ${\Omega }^{\infty }$-infinite representation type

Marcos Barrios, Gustavo Mata

Co-Gorenstein algebras were introduced by A. Beligiannis in \cite{B}. In \cite{KM}, the authors propose the following conjecture (Co-GC): if ${\Omega }^n(\mathrm{mod}A)$ is extension closed for…
