We study flips in hypertriangulations of planar points sets. Here a level- hypertriangulation of points in the planes is a subdivision induced by the projection of a -hyp…

Identifying cobordisms using kernel persistence
Yossi Bokor Bleile, Lisbeth Fajstrup, Teresa Heiss +2
Motivated by applications in chemistry, we give a homlogical definition of tunnels, or more generally cobordisms, connecting disjoint parts of a cell complex. For a filtered comple…
