Frobenius functors and one-sided Hopf algebras in braided monoidal categories
Lucrezia Bottegoni, Davide Ferri, Paolo Saracco
Evidence suggests a tight connection between the existence of antipode-like maps on bialgebra-like structures, and the Frobenius property for the associated free Hopf module functo…

On quiver skew braces, their ideals and products
Davide Ferri
Quiver skew braces or skew bracoids are equivalent to braided groupoids, that is, groupoids with a constraint of abelianity. They are the quiver-theoretic version of skew braces, a…
