Given a finite dimensional hereditary algebra Λ over a finite field k, in the derived category D b (Λ) we obtain some formulae on Hall numbers associated to triangles. Using them we prove that, for any tilted algebra Γ of Λ, there is an embedding of the twisted Ringel-Hall algebra of Γ into the Drin
We classify the finite-dimensional algebras over an algebraically closed field whose bounded derived category does not admit an infinite continuous family of pairwise non-isomorphic indecomposable complexes.
## Abstract In this paper we study the category of hyper MV‐algebras and we prove that it has a terminal object and a coequalizer. We show that Jia's construction can be modified to provide a free hyper MV‐algebra by a set. We use this to show that in the category of hyper MV‐algebras the monomorph
