Let S 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 a representative point for each connected component of S 0. For this purpose we exhibit explicit polynomial equations that describe the generic polar varieties of S 0. This… (More)

In this paper we apply for the rst time a new method for multivariate equation solving which was developed in 18], 19], 20] for complex root determination to the real case. Our main result concerns the problem of nding at least one representative point for each connected component of a real compact and smooth hypersurface. The basic algorithm of 18], 19],… (More)

The objective of this paper is to show how the recently proposed method by Giusti, Heintz, Morais, Morgenstern, Pardo [10] can be applied to a case of real polynomial equation solving. Our main result concerns the problem of finding one representative point for each connected component of a real bounded smooth hypersurface. The algorithm in [10] yields a… (More)
