bibo_abstract:
- Given a locally finite X⊆Rd and a radius r≥0, the k-fold cover of X and r consists
of all points in Rd that have k or more points of X within distance r. We consider
two filtrations—one in scale obtained by fixing k and increasing r, and the other
in depth obtained by fixing r and decreasing k—and we compute the persistence
diagrams of both. While standard methods suffice for the filtration in scale,
we need novel geometric and topological concepts for the filtration in depth.
In particular, we introduce a rhomboid tiling in Rd+1 whose horizontal integer
slices are the order-k Delaunay mosaics of X, and construct a zigzag module of
Delaunay mosaics that is isomorphic to the persistence module of the multi-covers.@eng
