Kernels of representations and coideal subalgebras of Hopf algebras
Sebastian Burciu
We define left and right kernels of representations of Hopf algebras. In the case of group algebras, left and right kernels coincide and they are the usual kernels of modules. In t…
More examples of invariance under twisting
Florin Panaite
We show that some more results from the literature are particular cases of the so-called "invariance under twisting" for twisted tensor products of algebras, for instance a result…
Invariance under twisting for crossed products
Florin Panaite
We prove a result of the type ''invariance under twisting'' for Brzezinski's crossed products, as a common generalization of the invariance under twisting for twisted tensor produc…
Algebra Structures Arising from Yang-Baxter Systems
Barbu R. Berceanu, Florin F. Nichita, Calin Popescu
Yang-Baxter operators from algebra structures appeared for the first time in [16], [17] and [8]. Later, Yang-Baxter systems from entwining structures were constructed in [5]. In th…
