Orthogonal polynomials and diffusion operators
We study the following problem: describe the triplets (Ω,g,μ) where g=(g ij (x)) is the (co)metric associated with the symmetric second order differential operator L(f)=1 ρ∑ ij ∂ i (g ij ρ∂ j f) defined on a domain Ω of ℝ d (that is L is a diffusion operator with …
