POLYNOMIAL MAPS OF AFFINE QUADRICS
"... Since the article [3] on polynomial maps of spheres appeared about 25 years ago, there have been a number of papers on the theory of rational maps of real varieties (see the references in [2], for example) which have many interesting things to say about the representation of homotopy classes by alge ..."

Unfolding polynomial maps at infinity
"... Let f: C n → C be a polynomial map. The polynomial describes a family of complex affine hypersurfaces f −1 (c), c ∈ C. The family is locally trivial, so the hypersurfaces have constant topology, except at finitely many irregular fibers f −1 (c) whose topology may differ from the generic or regular f ..."

Moduli space of polynomial maps
"... In the study of the dynamics of a polynomial map $f $ , the eigenvalues of the fixed points of $f $ play a very important role to characterize the original map $f $. In this paper, we shall study how many affine conjugacy classes of polynomial maps are there when the eigenvalues of their fixed point ..."

NONCOMMUTATIVE POLYNOMIAL MAPS
"... Polynomial maps attached to polynomials of an Ore extension are naturally defined. In this setting we show the importance of pseudolinear transformations and give some applications. In particular, factorizations of polynomials in an Ore extension over a finite field Fq[t; θ], where θ is the Frobeni ..."

"... Let F be a polynomial mapping from C n to C q with n> q. We study the De Rham cohomology of its fibres and its relative cohomology groups, by introducing a special fibre F −1 (∞) ”at infinity ” and its cohomology. Let us fix a weighted homogeneous degree on C[x1,...,xn] with strictly positive wei ..."

"... 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 ..."

An Inequality for Polynomial Mappings
 Bull. Ac. Pol.: Math

"... Abstract. We give an estimate of the growth of a polynonial mapping of C n. 1. Main result. Let F = (F1,...,Fn) : Cn → Cn be a polynomial mapping. We put d(F) = #F −1 (w) for almost all w ∈ Cn and call d(F) the geometric degree of F. Let di = deg Fi for i = 1,...,n. Then 0 ≤ d(F) ≤ ∏n i=1 di if Fi ..."
