... a long time ago that the computation of the decompositon of the Kronecker product χ (n−a,λ 2 , ) ⊗ χ (n−b,µ 2 , ) of two irreducible characters of the symmetric group into irreducibles depends ... µ, ν of n we denote by c(λ, µ, ν):=χ λ ⊗χ µ ,χ ν  (1) the multiplicity of χ ν in the Kronecker product χ λ ⊗ χ µ . F. Murnaghan observed in [6] that the computa...

... G → H (ε  r) the induced map  f : V (G) → V (H) is a bijection between the set of vertices of G and the set of vertices of H. We now show that given any pair a, b of vertices of G (which might ... coincide), the set E(a, b) of edges between these vertices is in one-to-one correspondence with the set E(  f(a),  f(b)) of edges between the images of the given...
