Tangential approximation of analytic sets
M. Ferrarotti, E. Fortuna, L. Wilson
Two subanalytic subsets of are called -equivalent at a common point if the Hausdorff distance between their intersections with the sphere centered at of r…
Algebraic approximation preserving dimension
Massimo Ferrarotti, Elisabetta Fortuna, Leslie Wilson
We prove that each semialgebraic subset of of positive codimension can be locally approximated of any order by means of an algebraic set of the same dimension. As a conseque…
Local algebraic approximation of semianalytic sets
Massimo Ferrarotti, Elisabetta Fortuna, Leslie Wilson
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…
Ideals of curves given by points
E. Fortuna, P. Gianni, B. Trager
Let C be an irreducible projective curve of degree d in Pn(K), where K is an algebraically closed field, and let I be the associated homogeneous prime ideal. We wish to compute gen…
