Kan Approximations of the Persistent Homology Transform

Shreya Arya, Justin Curry

The persistent homology transform (PHT) of a subset $M \subset R^{d}$ is a map $PHT (M) : S^{d - 1} \to Dgm$ from the unit sphere to the space of persist…

Decomposing the Persistent Homology Transform of Star-Shaped Objects

Shreya Arya, Barbara Giunti, Abigail Hickok +3

In this paper, we study the geometric decomposition of the degree- $0$ Persistent Homology Transform (PHT) as viewed as a persistence diagram bundle. We focus on star-shaped objects…

A Sheaf-Theoretic Construction of Shape Space

Shreya Arya, Justin Curry, Sayan Mukherjee

We present a sheaf-theoretic construction of shape space -- the space of all shapes. We do this by describing a homotopy sheaf on the poset category of constructible sets, where ea…
