Orthogonal Polynomials

← Back to Domain-Specific Abstractions by Domain

2 domain-specific abstractions whose origin domain is Orthogonal Polynomials.

• Bochner's theorem (orthogonal polynomials) — A classification theorem identifying the classical orthogonal-polynomial sequences that are eigenfunctions of a second-order differential operator with polynomial coefficients.
• Christoffel–Darboux formula — An identity collapsing a finite weighted sum of products of orthogonal polynomials into a quotient involving only two consecutive polynomial degrees.
