Abstract
Suppose that G is a finite group and D(G) the double algebra of G. For a given subgroup H of G, there is a sub-Hopf algebra D(G;H) of D(G). This paper gives the concrete construction of a D(G;H)-invariant subspace script A signH in field algebra of G-spin model and proves that if H is a normal subgroup of G, then script A sign H is Galois closed.
