Irreducibility and compositeness in q-deformed harmonic oscillator algebras
(Kluwer Academic/plenum Publ, 2002-09-01)
A study of the reducibility of the Fock space representation of the q-deformed harmonic oscillator algebra for real and root of unity values of the deformation parameter is carried out by using the properties of the Gauss ...
Lp-operator algebras associated with oriented graphs
(Theta Foundation, 2018-04)
For each 1 ≤ p < ∞ and each countable oriented graph Q we introduce an L p -operator algebra O p (Q) which contains the Leavitt path C-algebra LQ as a dense subalgebra and is universal for those L p -representations of LQ ...

Q-deformed fermionic Lipkin model at finite temperature
(1997-08-15)
The interplay between temperature and q-deformation in the phase transition properties of many-body systems is studied in the particular framework of the collective q-deformed fermionic Lipkin model. It is shown that in ...
Multiparameter twisted Weyl algebras
(ACADEMIC PRESS INC ELSEVIER SCIENCESAN DIEGO, 2012-05-01)
We introduce a new family of twisted generalized Weyl algebras, called multiparameter twisted Weyl algebras, for which we parametrize all simple quotients of a certain kind. Both Jordan's simple localization of the ...
Cohomología de Hochschild y estructura de Gerstenhaber de las álgebras toupie
(UR.FC, 2015)
In this thesis we compute the Hochschild cohomology H∗(A) of a certain type of algebras calledtoupie algebras, and we describe the Gerstenhaber structure of ⊕1i=0 Hi(A). A quiver Q is called toupie if it has a unique source ...
An introduction to Nichols Algebras
(Springer International Publishing, 2018)
Nichols algebras, Hopf algebras in braided categories with distinguishedproperties, were discovered several times. They appeared for the first time in the thesis of W. Nichols [72], aimed to construct new examples of Hopf ...
