On Separable and Frobenius Cowreaths of type
Fabio Renda
Cowreaths of type have been investigated in [10,19-21,27] as examples of (h-)separable and Frobenius coalgebras in monoidal categories. They are…

Infinitesimal -matrices for some families of Hopf algebras
Lucrezia Bottegoni, Fabio Renda, Andrea Sciandra
Given a bialgebra such that the associated trivial topological bialgebra admits a quasitriangular structure $\tilde{\mathcal{R}}=\mathcal{R}(1\otimes 1+\hbarÏ+\ma…

Separable cowreaths in higher dimension
Fabio Renda
In this paper we present an infinite family of (h-)separable cowreaths with increasing dimension. Menini and Torrecillas proved in [20] that for , a four-dimension…

E(n)-coactions on semisimple Clifford algebras
Fabio Renda
In this article we prove that -coactions over a finite-dimensional algebra are classified by tuples consisting of an involution and a family $…
