(INSTITUTE OF MATHEMATICS · POLISH ACADEMY OF SCIENCES, 2008)We classify, up to derived (equivalently, tilting-cotilting) equivalence all nondegenerate gentle two-cycle algebras. We also give a partial classification and formulate a conjecture in the degenerate case.
-
(Springer Berlin Heidelberg, 2012)Average path length is recognised as one of the vital characteristics of random graphs and complex networks. Despite a rather sparse structure, some cases were reported to have a relatively short lengths between every pair ...
-
(The London Mathematical Society, 2012)We describe the structure of semi-regular Auslander-Reiten components of artin algebras without external short paths in the module category. As an application we give a complete description of self-injective artin ...
-
(American Mathematical Society, 2012)We provide su cient conditions for a component of the Auslander- Reiten quiver of an artin algebra to be determined by the composition factors of its indecomposable modules
-
(Springer Berlin Heidelberg, 2012-04-29)In this work we study a simplified model of a neural activity flow in networks, whose connectivity is based on geometrical embedding, rather than being lattices or fully connected graphs. We present numerical results showing ...
-
(Springer, 2013)We provide an affirmative answer for the question raised almost twenty years ago in [22] concerning the characterization of tilted artin algebras by the existence of a sincere finitely generated module which is not the ...
-
(2013-01-20)W rozprawie podano pełen opis klas Morita równoważności wszystkich spójnych, samoinjektywnych algebr artinowskich, dla których kołczan Auslandera-Reiten zawiera rodzinę quasi-rur mającą wspólne składniki kompozycyjne, ...
-
(2013-01-21)We give a complete description of all self-injective artin algebras of infinite representation type whose component quiver has no short cycles.
-
(2013-01-24)We give a complete description of nitely generated modules over artin alge- bras which are not the middle of a short chain of modules, using injective and tilting modules over hereditary artin algebras.
-
(2013-01-24)We describe the structure of module categories of finite dimensional al- gebras over an algebraically closed field for which the cycles of nonzero noniso- morphisms between indecomposable finite dimensional modules are ...
-
(2013-04-17)Próba zdefiniowania pojęcia rozwiązania dla gier dwuosobowych symetrycznych, dla którego istniałoby pojęcie wartości gry i które zachowywałoby się dobrze w tak paradoksalnych sytuacjach jak dylemat podróżnika. Pomimo ...
-
(2013-04-17)Badania w klasie gier symetrycznych dwuosobowych w postaci normalnej. Redefinicja optimum Pareto w taki sposób, by było ono odporne na zdrady współgracza w ramach przyjętego protokołu z pełną komunikacją. Określenie ...
-
(Springer Berlin Heidelberg, 2013-06-09)In this work we provide a spectral comparison of functional networks in fMRI data of brain activity and artificial energy-based neural model. The spectra (set of eigenvalues of the graph adjacency matrix) of both networks ...
-
(2013-11-25)We solve a long standing open problem concerning the structure of finite cycles in the category $\mo A$ of finitely generated modules over an arbitrary artin algebra $A$, that is, the chains of homomorphisms $M_0 \buildrel ...
-
(Versita, 2014)We prove that the number of terms in the middle of an almost split sequence in the module category of a cycle-finite artin algebra is bounded by 5.
-
(Springer, 2015)We determine the Krull dimension of the module category of finite dimensional tame generalized multicoil algebras over an algebraically closed field, which are domestic.
-
(World Scientific Publishing Company, 2017)We study the composition of irreducible morphisms between indecomposable modules lying in quasi-tubes of the Auslander-Reiten quivers of artin algebras in relation with the powers of the radical of their module category.
-
(2017)We study topological bifurcations of critical orbits of equivariant gradient equations. We give necessary and sufficient conditions for the existence of global bifurcations of solutions of these equations. Moreover, we ...
