A graph theoretic model for the derived categories of gentle algebras and their homological bilinear forms
Jesús Arturo Jiménez González, Andrzej Mróz
We customize the existing models for the bounded derived category of gentle algebras to obtain simple graph theoretic tools to analyze indecomposable objects, Auslander-Reiten tria…
Bidirected graphs, integral quadratic forms and some Diophantine equations
Jesús Arturo Jiménez González, Andrzej Mróz
Bidirected graphs are multigraphs where every edge has an independent direction at each end. In the paper, with an arbitrary bidirected graph we associate a non-negative integral q…
Two nondeterministic positive definiteness tests for unidiagonal integral matrices
Andrzej Mróz
For standard algorithms verifying positive definiteness of a matrix based on Sylvester's criterion, the computationally pessimistic case is this when…
The dimensions of the homomorphism spaces to indecomposable modules over the four subspace algebra
Andrzej Mróz
This is the addendum to the paper "On the Multiplicity Problem and the Isomorphism Problem for the Four Subspace Algebra" Communications in Algebra, 40:6 (2012), 2005-2036 (DOI: 10…
