Positive polynomials on fibre products
نویسندگان
چکیده
Recent investigations in optimization theory concerning the structure of positive polynomials with a sparsity pattern are interpreted in the more invariant language of (iterated) fibre products of real algebraic varieties. This opens the perspective of treating on a unifying basis the cases of positivity on unbounded supports, on non-semialgebraic supports, or of polynomials depending on countably many variables.

Fibre products of supersingular curves and the enumeration of irreducible polynomials with prescribed coefficients
For any positive integers n ≥ 3, r ≥ 1 we present formulae for the number of irreducible polynomials of degree n over the finite field F2r where the coefficients of xn−1, xn−2 and xn−3 are zero. Our proofs involve counting the number of points on certain algebraic curves over finite fields, a technique which arose from Fourier-analysing the known formulae for the F2 base field cases, reverse-en...

متن کاملFull Quadrature Sums for Generalized Polynomials with Freud Weights
Generalized nonnegative polynomials are defined as products of nonnegative polynomials raised to positive real powers. The generalized degree can be defined in a natural way. In this paper we extend quadrature sums involving pth powers of polynomials to those for generalized polynomials.
متن کاملRational Polynomials of Simple Type
A polynomial map f : C2 → C is rational if its generic fibre, and hence every fibre, is of genus zero. It is of simple type if, when extended to a morphism f̃ : X → P1 of a compactification X of C2, the restriction of f̃ to each curve C of the compactification divisor D = X − C2 is either degree 0 or 1. The curves C on which f̃ is non-constant are called horizontal curves, so one says briefly “eac...
متن کاملWarped product and quasi-Einstein metrics
Warped products provide a rich class of physically significant geometric objects. Warped product construction is an important method to produce a new metric with a base manifold and a fibre. We construct compact base manifolds with a positive scalar curvature which do not admit any non-trivial quasi-Einstein warped product, and non compact complete base manifolds which do not admit any non-triv...
