Conormal Spaces and Whitney Stratifications

Helmer, M., & Nanda, V. (2022, June 14). FOUNDATIONS OF COMPUTATIONAL MATHEMATICS.

By: M. Helmer n & V. Nanda *

author keywords: Whitney stratification; Conormal variety; Ideal saturation
TL;DR: A new algorithm for computing Whitney stratifications of complex projective varieties using an algebraic criterion, due to Lê and Teissier, and a new interpretation of this conormal criterion via ideal saturations, which can be practically implemented on a computer. (via Semantic Scholar)
