WebMay 18, 2024 · Great Orthogonality Theorem Identity (group theory) Let G be a group of or order n with Γ matrix representations. We define the vector ψ g ( Γ, i, k) = d Γ n D i k Γ ( g) where ( Γ, i, k) is a label, with i, k ∈ 1,..., d Γ, and where the group element g indexes the components of ψ. The GOT can then be restated as an orthonormality ... This theorem is also known as the Great (or Grand) Orthogonality Theorem. Every group has an identity representation (all group elements mapped onto the real number 1). This is an irreducible representation. The great orthogonality relations immediately imply that See more In mathematics, the Schur orthogonality relations, which were proven by Issai Schur through Schur's lemma, express a central fact about representations of finite groups. They admit a generalization to the case of See more Intrinsic statement The space of complex-valued class functions of a finite group G has a natural inner product: See more The generalization of the orthogonality relations from finite groups to compact groups (which include compact Lie groups such as SO(3)) is basically simple: Replace the summation over the group by an integration over the group. Every compact group See more
