Birational Reparametrizations of Surfaces
Jorge Caravantes, Sonia Pérez-Díaz, J. Rafael Sendra
Given a unirational parameterization of a surface, we present a general algorithm to determine a birational parameterization without using parameterization algorithms. Additionally…
Computing Birational Polynomial Surface Parametrizations without Base Points
Sonia Pérez-Díaz, J. Rafael Sendra
In this paper, we present an algorithm for reparametrizing birational surface parametrizations into birational polynomial surface parametrizations without base points, if they exis…
On the base point locus of surface parametrizations: formulas and consequences
David A. Cox, Sonia Pérez-Díaz, J. Rafael Sendra
This paper shows that the multiplicity of the base points locus of a projective rational surface parametrization can be expressed as the degree of the content of a univariate resul…
Resultants and Singularities of Parametric Curves
Angel Blasco, Sonia Pérez-Díaz
Let be an algebraic space curve defined parametrically by . In this paper, we introduce a polynomial, the T--function, ,…
