RT info:eu-repo/semantics/article T1 Computing the form of highest degree of the implicit equation of a rational surface A1 Alcázar Arribas, Juan Gerardo A1 Pérez Díaz, Sonia K1 Highest order form K1 Surface implicitization K1 Rational surface K1 Matemáticas K1 Mathematics AB A method is presented for computing the form of highest degree of the implicit equation of a rational surface, defined by means of a rational parametrization. Determining the form of highest degree is useful to study the asymptotic behavior of the surface, to perform surface recognition, or to study symmetries of surfaces, among other applications. The method is efficient, and works generally better than known algorithms for implicitizing the whole surface, in the absence of base points blowing up to a curve at infinity. Possibilities to compute the form of highest degree of the implicit equation under the presence of such base points are also discussed. We provide timings to compare our method with known methods for computing the whole implicit equation of the surface, both in absence and in presence of base points blowing up to a curve at infinity.
