On the Degree in Categories of Complexes of Fixed Size
(Springer, 2019-02-01)
[Abstract]: We consider Λ an artin algebra and n ≥ 2. We study how to compute the left and right degrees of irreducible morphisms between complexes in a generalized standard Auslander-Reiten component of Cn(proj Λ) with ...
