Uniform foliations with Reeb components
Joaquín Lema
A foliation on a compact manifold is uniform if each pair of leaves of the induced foliation on the universal cover are at finite Hausdorff distance from each other. We study unifo…
Electronic properties of substitutional impurities in graphene-like CN, -CN, and -CN
Saif Ullah, Pablo A. Denis, Marcos G. Menezes +2
We study the electronic and structural properties of substitutional impurities of graphenelike nanoporous materials CN, -, and -CN by means of density functiona…
The Lie bialgebra structure of the vector space of cyclic words
Ana González
In this paper we give a combinatory proof of the Lie bialgebra structure presented in the vector space of reduced cyclic words. This structure was introduce by M. Chas in Combinato…
Yetter-Drinfeld modules under cocycle twists
Georgia Benkart, Mariana Pereira, Sarah Witherspoon
We give an explicit formula for the correspondence between simple Yetter-Drinfeld modules for certain finite-dimensional pointed Hopf algebras and those for cocycle twists $H^σ…
Factorization of simple modules for certain pointed Hopf algebras
Mariana Pereira
We study the representations of two types of pointed Hopf algebras: restricted two-parameter quantum groups, and the Drinfel'd doubles of rank one pointed Hopf algebras of nilpoten…
