Localized Polynomial Frames on the Interval with Jacobi Weights
As is well known the kernel of the orthogonal projector onto the polynomials of degree n in L2(wα,β , [−1, 1]) with wα,β(t) = (1−t) (1+t) can be written in terms of Jacobi polynomials. It is shown that if the coefficients in this kernel are smoothed out by sampling a C∞ function then the resulting function has nearly exponential (faster than any polynomial) rate of decay away from the main diag...
متن کاملLocalized Polynomial Frames on the Ball
Abstract. Almost exponentially localized polynomial kernels are constructed on the unit ball Bd in Rd with weights wμ(x) = (1−|x |2)μ−1/2, μ ≥ 0, by smoothing out the coefficients of the corresponding orthogonal projectors. These kernels are utilized to the design of cubature formulas on Bd with respect to wμ(x) and to the construction of polynomial tight frames in L2(Bd , wμ) (called needlets)...
متن کاملConstrained Approximation with Jacobi Weights
In this paper, we prove that for l = 1 or 2 the rate of best l-monotone polynomial approximation in the Lp norm (1 ≤ p ≤ ∞) weighted by the Jacobi weight wα ,β(x) ∶= (1 + x)α(1 − x)β with α, β > −1/p if p <∞, or α, β ≥ 0 if p =∞, is bounded by an appropriate (l + 1)-st modulus of smoothness with the same weight, and that this rate cannot be bounded by the (l+2)-ndmodulus. Related results on con...
متن کاملPolynomial frames on the sphere
We introduce a class of polynomial frames suitable for analyzing data on the surface of the unit sphere of a Euclidean space. Our frames consist of polynomials, but are well localized, and are stable with respect to all the Lp norms. The frames belonging to higher and higher scale wavelet spaces have more and more vanishing moments. 1 ∗The research of this author was supported, in part, by gran...
متن کاملMultivariate Jacobi polynomials with singular weights
First we give a compact treatment of the Jacobi polynomials on a simplex in IR which exploits and emphasizes the symmetries that exist. This includes the various ways that they can be defined: via orthogonality conditions, as a hypergeometric series, as eigenfunctions of an elliptic pde, as eigenfunctions of a positive linear operator, and through conditions on the Bernstein–Bézier form. We the...
