Symmetric functions and the Vandermonde matrix

Abstract: This work deduces the lower and the upper triangular factors of the inverse of the Vandermonde matrix using symmetric functions and combinatorial identities. The L and U matrices are in turn factored as bidiagonal matrices. The elements of the upper triangular matrices in both the Vandermonde matrix and its inverse are obtained recursively. The particular valuex i = 1 + q + · · · + q i−1 in the indeterminates of the Vandermonde matrix is investigated and it leads to q-binomial and q-Stirling matrices. It is al… Show more

“…In this section we report some results concerning the factorization of a Vandermonde matrix (actually, its transpose), to be used later: though most of them are known (see, for example, [1,9,14,15]), nevertheless, they are here cast in the most general and appropriate form for subsequent reference.…”

“…This clever selection of the nodes reduces the solution of the interpolation problem to the solution of a linear system of order N whose coefficient matrix is the transpose of a nonsingular (since different monomials evaluate to different values) Vandermonde matrix (see, for example, [17] for the expression of the Vandermonde matrix).…”

“…Since the operator ∆ i q1 ∆ j q2 annihilates any polynomial of total degree less than i+j, we see from (4.5) that B m,n (x r y s ; x, y) is a polynomial of total degree min(m + n, r + s). It is shown in [5] that the q-Bernstein polynomial of univariate monomial functions involve the q-Stirling numbers of the second kind S q (k, l), where Note that the q-Stirling numbers of the second kind S q (k, l) also appears in the triangular factorization of the Vandermonde matrix with the geometrically spaced knots, [8]. Another useful representation of (4.7) may be deduced from [11,Chap.…”
