摘要: Let H be a finite dimensional Hopf C-algebra, and let K be a Hopf *-subalgebra of H. Considering that the field algebra FK of a non-equilibrium Hopf spin model carries a D(H,K)-invariant subalgebra AK, this paper shows that the C-basic construction for the inclusion AKFK {can be expressed as} the crossed product C-algebra FKD(H,K). Here, D(H,K) is a bicrossed product of the opposite dual Hop^ and K. Furthermore, the natural action of D(H,K)^ on D(H,K) gives rise to the iterated crossed product FKD(H,K)D(H,K)^, which coincides with the C-basic construction for the inclusion FKFKD(H,K). In the end, the Jones type tower of field algebra FK is obtained, and the new field algebra emerges exactly as the iterated crossed product.
