A Cacti theoretical interpretation of the axioms of bialgebras and H-module algebras
(Elsevier Inc, 2015-04)
We establish a dictionary between the Cacti algebra axioms on a Cacti algebra structure with underlying free associative algebra, under suitable good behavior with degrees. Using these ideas, for an associative algebra A ...
PBW-deformations and deformations à la Gerstenhaber of N-Koszul algebras
(European Mathematical Society, 2014-07)
In this article we establish an explicit link between the classical theory of deformations à la Gerstenhaber (and a fortiori with the Hochschild cohomology) and (weak) PBW-deformations of homogeneous algebras. Our point ...

Calculations of BV-Algebra structures on Hochschild (Co)homology and string topology of classifying spaces
(Universidad de los AndesDoctorado en MatemáticasFacultad de CienciasDepartamento de Matemáticas, 2017)
"La cohomología de Hochschild de un álgebra asociativa tiene una estructura algebráica muy amplia. Es un álgebra graduada, un álgebra de Gerstenhaber y bajo condiciones adecuadas es un álgebra de Batalin-Vilkovisky. En ...
On the classification of commutative right-nilalgebras of dimension at most four
(2007)
Gerstenhaber and Myung (1975) classified all commutative, power-associative nilalgebras of dimension 4. In this article we extend Gerstenhaber and Myung's results by giving a classification of commutative right-nilalgebras ...
On the classification of commutative right-nilalgebras of nilindex 5 and dimension 4
(TAYLOR & FRANCIS INC, 2008-05)
Gerstenhaber and Myung (1975) classified all commutative power-associative nilalgebras of dimension 4. In Elduque and Labra (2007), Gerstenhaber and Myung's results are generalized by giving a classification of commutative ...
