Questions in which polynomials (single or several variables) play a key role. It is typically important that this tag is combined with other tags; polynomials appear in very different contexts. Please, use at least one of the top-level tags, such as nt.number-theory, co.combinatorics, ac.commutative-algebra, in addition to it. Also, note the more specific tags for some special types of polynomials, e.g., orthogonal-polynomials, symmetric-polynomials.

A Generalization of Hadamard?
Suppose that $F(x,y) = (f(x,y),g(x,y))$ is a polynomial map from $\mathbb{R}^2$ to $\mathbb{R}^2$. Assume it is locally at most $k$-to-1. If the map $F(x,y)$ is $proper$, then Hadamard's Theorem shows …
