Abstract:

This paper is devoted to the following result: let R be a real closed field and let S be a semialgebraic subset of Rn defined by a boolean combination of polynomial inequalities. Let D be the sum of the degrees of the polynomials involved. Then it is possible to find algorithmically a description of the semialgebraically connected components of S in sequential time Dn o(1) and parallel time (n log D)o(1) This implies that the problem of finding the connected components of a semialgebraic set can be solved in P-SPACE. © 1994 Springer-Verlag New York Inc.
