Title Stiefel-Whitney Classes and Persistent Stiefel-Whitney Classes
Abstract Persistent homology has emerged as a fundamental and important tool in topological based data analysis, which has found applications in many fields such as medicine, image processing, biology, network analysis, material science, sensor network. Persistent cohomology has consequently, also been found to be useful in the theory of data analysis. The goal of this talk is to present the notion of  special cohomology classes, the Stiefel-Whitney characteristic classes and persistence in the classes.
