Great orthogonality theorem
WebSome of the most useful aspects of group theory for applications to physical problems stem from the orthogonality relations of characters of irreducible representations. The widespread impact of these relations stems from their role in constructing and resolving new representations from direct products of irreducible representations. Web∫dU D** X (U) ⊗ D** Y (U-1) = δ** XY δ ik δ jl / d(X) (the great orthogonality theorem)and sum over X,Y . But the problem is, some times the decomposition gives several copies of the same irreps, which are most likely in different bases and break down the orthogonality relation. How do we justify the orthogonality theorem in this case?
