Course Description

Overview

Explore the reconstruction of topological properties in compact metric spaces through a comprehensive lecture on approximation techniques. Delve into inverse sequences of finite topological spaces and polyhedra derived from finite approximations. Discover the connections between this construction, Borsuk's Theory of Shapes, and Topological Persistence, a robust tool in Topological Data Analysis for extracting features from noisy datasets. Learn about the Hawaiian Earring, Cech homology, finite spaces, posets, and simplicial complexes. Examine the main construction of Polyhedral Approximative Sequences and investigate inverse persistence, infinite approximations, and the relationship between inverse limits and Shape theory.
