Diamond operator

From Wikipedia, the free encyclopedia

In number theory, the diamond operatorsd〉 are operators acting on the space of modular forms for the group Γ1(N), given by the action of a matrix (a b
c δ
)
in Γ0(N) where δ ≈ d mod N. The diamond operators form an abelian group and commute with the Hecke operators.
