Whitney, Kuo-Verdier and Lipschitz stratifications for the surfaces y^a = t^b x^c +x^d
Résumé
We specify the canonical stratifications satisfying respectively Whitney (a)-regularity, Whitney (b)-regularity, Kuo Verdier (w)-regularity, and (L)-regularity for the family of surfaces y(a) = z(b)x(c) + x(d), where a, b, c, d are positive integers, in both the real and complex cases.
