I am interested in Hopf algebras and Nichols algebras. I study
their classification and their representation theory.
In this framework, my favorite algebras are the Fomin-Kirrilov algebras
\(FK_n\)
and the generalized small quantum groups.
Two paradigmatic problems are surrounding my works and involve these algebras.
First, it is not known whether or not
the Fomin-Kirillov algebras are finite or infinite dimensional for \(n \geq 6\). Second, most of my recent works are about
the representation theory of generalized small quantum groups. In the examples, I have observed that the Hilbert series
of their simple modules are palindromic and I would like to verify if this property holds true in general.
