【 摘 要 】

Given a parametrization of a rational plane algebraic curve C, some explicit adjoint pencils on C are described in terms of determinants. Moreover, some generators of the Rees algebra associated to this parametrization are presented. The main ingredient developed in this paper is a detailed Study of the elimination ideal of two homogeneous polynomials in two homogeneous variables that form a regular sequence.
