"Barcodes" for continuous maps and a brief introduction to Alternative Morse Theory
Dan Burghelea · arXiv (Cornell University) · 2023
This paper reviews the description of "bar codes" for a continuous real-valued map and explains how to recover the Morse complex of a Morse function from them. In this presentation the bar codes appear as the support of two vector-space valued maps, one defined on the Euclidean plane and the other on the "above diagonal" half plane.
