Waring’s Problem for Polynomials in Two Variables
We prove that all polynomials in several variables can be decomposed as the sums of kth powers: P (x1, . . . , xn) = Q1(x1, . . . , xn) + · · ·+Qs(x1, . . . , xn), provided that elements of the base field are themselves sums of kth powers. We also give bounds for the number of terms s and the degree of the Qi . We then improve these bounds in the case of two variables polynomials of large degre...

متن کاملOrthogonal Polynomials for Potentials of two Variables with External Sources
This publication is an exercise which extends to two variables the Christoffel’s construction of orthogonal polynomials for potentials of one variable with external sources. We generalize the construction to biorthogonal polynomials. We also introduce generalized Schur polynomials as a set of orthogonal, symmetric, non homogeneous polynomials of several variables, attached to Young tableaux.
متن کاملIrregular fibers of complex polynomials in two variables
Let f : C −→ C be a polynomial. The bifurcation set B for f is the minimal set of points of C such that f : C \f−1(B) −→ C\B is a locally trivial fibration. For c ∈ C, we denote the fiber f−1(c) by Fc. The fiber Fc is irregular if c is in B. If s / ∈ B, then Fs is a generic fiber and is denoted by Fgen . The tube Tc for the value c is a neighborhood f −1(D2 ε(c)) of the fiber Fc, where D 2 ε(c)...
متن کاملNontrivial Rational Polynomials in Two Variables Have Reducible Fibres
We shall call a polynomial map f : C → C a “coordinate” if there is a g such that (f, g) : C → C is a polynomial automorphism. Equivalently, by AbhyankarMoh and Suzuki, f has one and therefore all fibres isomorphic to C. Following [7] we call a polynomial f : C → C “rational” if the general fibres of f (and hence all fibres of f) are rational curves. The following theorem, which says that a rat...
