We consider a symmetric minimal relation L₀ generated by an integral equation with operators measures. We describe the generalized resolvents of L₀ using the characteristic function M(λ) (λ ∈ ℂ), i.e.

Let A = (A₁,...,An) and B = (B₁,...,Bn) be row contractions on Hilbert spaces 𝓗₁ and 𝓗₂, respectively, and L be a contraction from D B = ran ¯ D B to D A * = ran ¯ D A * where DB = (I – B*B)1/2 and ...
