Remarks on polynomial parametrization of sets of integer points
Sophie Frisch
If, for a subset S of Z^k, we compare the conditions of being parametrizable (a) by a single k-tuple of polynomials with integer coefficients, (b) by a single k-tuple of integer-va…

Parametrization of Pythagorean triples by a single triple of polynomials
Sophie Frisch, Leonid Vaserstein
It is well known that Pythagorean triples can be parametrized by two triples of polynomials with integer coefficients. We show that no single triple of polynomials with integer coe…
