The Gorenstein-projective modules over a monomial algebra
Xiao-Wu Chen, Dawei Shen, Guodong Zhou
We classify indecomposable non-projective Gorenstein-projective modules over a monomial algebra via the notion of perfect paths. We apply this classification to a quadratic monomia…

The singularity category of a Nakayama algebra
Dawei Shen
Let be a Nakayama algebra. We give a description of the singularity category of inside its stable module category. We prove that there is a duality between the singularity…
