Two subanalytic subsets of [math] are called [math] -equivalent at a common point [math] if the Hausdorff distance between their intersections with the sphere centered at [math] of radius [math] vanishes to order [math] as [math] tends to [math] . We

Given a real algebraic surface $S$ in $\pro$, we propose a procedure to determine the topology of $S$ and to compute non-trivial topological invariants for the pair $(\pro, S)$ under the hypothesis that the real singularities of $S$ are isolated. In

Two subanalytic subsets of R^n are called s-equivalent at a common point P if the Hausdorff distance between their intersections with the sphere centered at P of radius r vanishes of order greater than s when r tends to 0. In this paper we prove that

This book starts with a concise but rigorous overview of the basic notions of projective geometry, using straightforward and modern language. The goal is not only to establish the notation and terminology used, but also to offer the reader a quick su

In this paper we show that the ideal of any algebraic curve in affine 3-space whose Jacobian matrix has rank at least 1 at every singular point of the curve can be generated by three polynomials and we give constructive procedures to compute such gen
