Abstract

This paper aims to introduce a filtration analysis of sampled maps based on\npersistent homology, providing a new method for reconstructing the underlying\nmaps. The key idea is to extend the definition of homology induced maps of\ncorrespondences using the framework of quiver representations. Our definition\nof homology induced maps is given by most persistent direct summands of\nrepresentations, and the direct summands uniquely determine a persistent\nhomology. We provide stability theorems of this process and show that the\noutput persistent homology of the sampled map is the same as that of the\nunderlying map if the sample is dense enough. Compared to existing methods\nusing eigenspace functors, our filtration analysis has an advantage that no\nprior information on the eigenvalues of the underlying map is required. Some\nnumerical examples are given to illustrate the effectiveness of our method.\n
