Cohomology of Trivial Linear Cycle Sets

Jorge Guccione, Juan José Guccione, Christian Valqui

We provide a complete classification of extensions of a trivial linear cycle set H by an abelian group I, under the assumption that both H and I are finite cyclic p-groups with p o…

Cohomology of Linear Cycle Sets when the adjoint group is finite abelian

Jorge Guccione, Juan José Guccione, Christian Valqui

This paper analyzes the second cohomology group of a linear cycle set with coefficients in an abelian group I, for linear cycle sets with commutative adjoint operation, focusing on…

Extensions of a family of Linear Cycle Sets

Jorge Guccione, Juan José Guccione, Christian Valqui

This paper explores the cohomology of linear cycle sets, focusing on extensions of a specific linear cycle set H by an abelian group I. We derive explicit formulas for the second c…

Hopf q-braces structures on rank one pointed Hopf algebras

Jorge A. Guccione, Juan J. Guccione, Christian Valqui

In this paper we determine all the Hopf q-brace structures on rank one pointed Hopf algebras and compute the socle of each one of them. We also identify which among them are Hopf s…

Number of homogeneous components of counterexamples to the Dixmier conjecture

Jorge Guccione, Juan Jose Guccione, Christian Valqui

Assume that and are elements of satisfying . The Dixmier Conjecture for says that they always generate . We show that if is a sum of not mor…

On two conjectures about the intersection of longest paths and cycles

Juan Gutiérrez, Christian Valqui

A conjecture attributed to Smith states that every pair of longest cycles in a -connected graph intersect each other in at least vertices. In this paper, we show that every…
