Covering Rational Ruled Surfaces
Published 9 Jun 2014 in math.AG and cs.SC | (1406.2140v3)
Abstract: We present an algorithm that covers any given rational ruled surface with two rational parametrizations. In addition, we present an algorithm that transforms any rational surface parametrization into a new rational surface parametrization without affine base points and such that the degree of the corresponding maps is preserved.
