Abstract:

The main work of this article is to give a nontrivial method to construct pointed semilattice graded weak Hopf algebra At =
ni=0A αt from a Clifford monoid S = [Y ; Gαφα, β ]by Ore-extensions, and to obtain a co-Frobenius semilattice graded weak Hopf algebra H(S, n, cχ, a, b) through factoring At by a semilattice graded weak Hopf ideal.
