Abstract
We display an existence of the short (polynomial size) proofs for nondivisibility of two sparse multivariate polynomials under the Extended Riemann Hyphothe-sis (ERH). The divisibility problem is closely related to the rational interpolation problem (whose complexity bounds were determined in [GKS 90] and [GK 91]). In this setting we assume that a rational function is given by a black box (see e.g. [KT 88, GKS 90, K 89]) for evaluating it. We prove also that, surprisingly, the problem of deciding whether a rational function given by a black box equals a polynomial belongs to the parallel class NC (see e.g. [KR 90]), provided we know the degree of some sparse representation of it.
