Shimura has studied the structure of the Hecke ring R(Δ,Γ) in the case Γ=SLn(Z)andΔΓis a subsemigroup of G =GLn(Q).Letpbe a prime and letΓ =GLn(Zp) Δ G =GLn( p),whereΔis a semigroup. In this paper, we shall determine the structure of the Hecke ringR(Δ,Γ)and its some properties.
Shimura has studied the structure of the Hecke ring R(A,F) in the case F = SLn(Z ) and △ Гis a subsemigroup of G =GLn(Q). Let p be a prime and let Г = GLn(Zp) △ G = GLn( Qp), where A is a semigroup. In this paper, we shall determine the structure of the Hecke ring R(△,Г) and its some properties.
