A first approach to generalized polar varieties

Bank, Bernd; Giusti, Marc; Heintz, Joos; Pardo, Luis-Miguel

Let W be a closed algebraic subvariety of the n-dimensional projective space over the complex or real numbers and suppose that W is non--empty and equidimensional. In this paper we generalize the classic notion of polar ...

Equations for Polar Varieties and Efficient Real Elimination

Bank, Bernd; Giusti, Marc; Heintz, Joos; Mbakop, G. M.

Let $V_0$ be a smooth and compact real variety given by a reduced regular sequence of polynomials $f_1,..., f_p$. This paper is devoted to the algorithmic problem of finding efficiently for each connected component of $V_0$ ...

Polar Varieties, Real Equation Solving and Data-Structures

Bank, Bernd; Giusti, Marc; Heintz, Joos; Mbakop, G. M.

In this paper we apply for the first time a new method for multivariate equation solving which was developed in for complex root determination to the real case. Our main result concerns the problem of finding at least one ...
