Projective resolutions of simple modules and Hochschild cohomology for incidence algebras
Viktor Bekkert, John William MacQuarrie, Júlio Marques
We give a practical, algorithmic method to calculate minimal projective resolutions of simple modules for a finite dimensional incidence -algebra , where is a field. We a…
Derived tame Nakayama algebras
Viktor Bekkert, Hernan Giraldo, Jose A. Velez-Marulanda
We determine the derived representation type of Nakayama algebras and prove that a derived tame Nakayama algebra without simple projective module is gentle or derived equivalent to…
Universal Deformation Rings of Finitely Generated Gorenstein-Projective Modules over Finite Dimensional Algebras
Viktor Bekkert, Hernan Giraldo, Jose Velez-Marulanda
Let be a field of arbitrary characteristic, let be a finite dimensional -algebra, and let be a finitely generated -module. F. M. Bleher and the…
On Singular Equivalences of Morita Type and Universal Deformation Rings for Gorenstein Algebras
Viktor Bekkert, Hernan Giraldo, Jose A. Velez-Marulanda
Let be a finite-dimensional algebra over a fixed algebraically closed field of arbitrary characteristic, and let be a finitely generated -module. It follows…
New Irreducible Modules for Heisenberg and Affine Lie Algebras
Viktor Bekkert, Georgia Benkart, Vyacheslav Futorny +1
We study -graded modules of nonzero level with arbitrary weight multiplicities over Heisenberg Lie algebras and the associated generalized loop modules over affine Kac-M…
Derived categories for algebras with radical square zero
Viktor Bekkert, Yuriy Drozd
We determine the derived representation types of algebras with radical square zero and give a description of the indecomposable objects in their bounded derived categories.
