The structure of the observable algebra determined by a Hopf *-subalgebra in Hopf spin models

Let H be a finite dimensional Hopf C*-algebra, H1 Hopf*-subalgebra of H. This paper focuses on the observable algebra AH1 determined by in nonequilibrium spin models, which there is copy each lattice site, and ? link, where denotes dual Furthermore, using iterated twisted tensor product +*-algebras, one can prove that algebraAH1 *-isomorphic to C*-inductive limit ... o .
