On the coefficients of Coxeter polynomials of trees and bipartite quivers
Niv Harel, Sefi Ladkani
We apply spectral graph theory and a theorem of A'Campo to express the first and second coefficients of the Coxeter polynomials associated with certain bipartite quivers in terms o…
Non-degenerate potentials on the quiver
Sefi Ladkani
We develop a method to compute certain mutations of quivers with potentials and use this to construct an explicit family of non-degenerate potentials on the exceptional quiver $X_7…
Refined Coxeter polynomials
Sefi Ladkani
Coxeter polynomials are important homological invariants that are defined for a large class of finite-dimensional algebras. It is of particular interest to develop methods to compu…
On derived equivalences for categories of generalized intervals of a finite poset
Frederic Chapoton, Sefi Ladkani, Baptiste Rognerud
We study two constructions related to the intervals of finite posets. The first one is a poset. The second one is more complicated. Loosely speaking it can be seen as a poset with…
From groups to clusters
Sefi Ladkani
We construct a new class of symmetric algebras of tame representation type that are also the endomorphism algebras of cluster tilting objects in 2-Calabi-Yau triangulated categorie…
Finite-dimensional algebras are (m>2)-Calabi-Yau-tilted
Sefi Ladkani
We observe that over an algebraically closed field, any finite-dimensional algebra is the endomorphism algebra of an m-cluster-tilting object in a triangulated m-Calabi-Yau categor…
