Braided crossed category over crossed group-cograded weak Hopf quasigroups
Huili Liu, Lingli Zhu, Tao Yang
In this paper, we generalizing the main result in Liu[10] to weak Hopf coquasigroups case. We first define and study group-cograded weak Hopf quasigroups, which generalize both gro…

Yetter-Drinfeld modules for group-cograded Hopf quasigroups
Huili Liu, Tao Yang, Lingli Zhu
Let be a crossed group-cograded Hopf quasigroup. We first introduce the notion of -Yetter-Drinfeld quasimodule over . If the antipode of is bijective, we show that th…
