Interpolating polynomial wavelets on [?1,1] [PDF]
The authors use a system of orthogonal polynomials with respect to the four Chebyshev weights, \(1/\sqrt(1-x^2)\), \(\sqrt(1-x^2)\), \(\sqrt{[(1-x)/(1+x)]}\) and \(\sqrt{[(1+x)/(1-x)]}\), with positive leading coefficients and Darboux kernels to construct four interpolating scaling functions and interpolating wavelets with a multiresolution structure ...

Corollary 15.10 assures that there is at most one polynomial of degree n and assuming preassigned values in n + 1 given complex numbers. What we still do not know is whether such a polynomial actually exists. For instance, does there exists a polynomial f with rational coefficients, degree 3 and such that f(0) = 1, f(1) = 2, f(2) = 3 and f(3) = 0?

On the convergence of interpolation polynomials
Analysis Mathematica, 1985Let \(\{x_{\nu}\}^ n_{\nu =1}\) be the roots of the polynomials \(\omega_ n(x)=-n(n-1)\int^{x}_{-1}P_{n-1}(t)dt=(1,x^ 2)P'_{n-1}(x),\quad\) \((n=2,3,...)\), where \(P_{n-1}(x)\) is the Legendre polynomial of degree \(n-1\) with the normalization \(P_{n-1}(1)=1\). Let also \(\{\xi_{\nu}\}^{n-1}_{\nu =1}\) be the roots of \(\omega'_ n(x)=-n(n-1)P_{n-1}(x)

Polynomials and Interpolations
2013If selected values of a function are given in a tabular representation, it is often desirable to obtain an easily computable formula which yields both those given values and approximations for in-between points, not included in the table. This procedure is called interpolation.

Polynomial and Rational Interpolation
1996Assume that we know n + 1 data points (x i , y i ), with \( x_i ,y_i \in \mathbb{R} \), for i = 0, …, n, in the form of a table of values.
