Nearly Frobenius dimension on Frobenius algebras
Dalia Artenstein, Ana González, Gustavo Mata
This article is divided into two parts. In the first part we work over a field and prove that the Frobenius space associated to a Frobenius algebra is generated as lef…

Nearly Frobenius theory and semisimplicity of bimodules
Dalia Artenstein, Ana González, Gustavo Mata
In the first part of this article we prove that one of the conditions required in the original definition of nearly Frobenius algebra, the coassociativity, is redundant. Also, we d…

Gerstenhaber structure on Hochschild cohomology of toupie algebras
Dalia Artenstein, Marcelo Lanzilotta, Andrea Solotar
We study homological properties of a family of algebras called toupie algebras. Our main objective is to obtain the Gerstenhaber structure of their Hochschild cohomology, with the…
