Polynomial Selections and Separation by Polynomials
By R, N we denote the set of all reals and positive integers, respectively. Let I ⊂ R be an interval. In this paper we present a necessary and sufficient condition under which two functions f, g : I → R can be separated by a polynomial of degree at most n, where n ∈ N is a fixed number. Our main result is a generalization of the theorem concerning separation by affine functions obtained recentl...

This paper deals with a result concerning the algebraic dual of the linear mapping defined by the multiplication of polynomial vectors by a given polynomial matrix over a commutative field
متن کاملOrthogonal Polynomials and Polynomial Approximations
3.1.1. Existence and uniqueness. Our immediate goal is to establish the existence of a sequence of orthogonal polynomials. Although we could, in principle, determine the coefficients a j of pn in the natural basis by using the orthogonality conditions (3.1.2), it is computationally advantageous to express pn in terms of lower-order orthogonal polynomials. Let us denote Pn := span { 1, x, x, · ·...
متن کاملPolynomial Minimum Root Separation
The minimum root separation of an arbitrary polynomial P is defined as the minimum of the distances between distinct (real or complex) roots of P. Some asymptotically good lower bounds for the root separation of P are given, where P may have multiple zeros. There are applications in the analysis of complexity of algorithms and in the theory of algebraic and transcendental numbers.
متن کاملGeneralizations of Chebyshev polynomials and Polynomial Mappings
In this paper we show how polynomial mappings of degree K from a union of disjoint intervals onto [−1, 1] generate a countable number of special cases of generalizations of Chebyshev polynomials. We also derive a new expression for these generalized Chebyshev polynomials for any genus g, from which the coefficients of xn can be found explicitly in terms of the branch points and the recurrence c...
