A spectrum of p-atic symmetries and defects in confluent epithelia
Lea Happel, Griseldis Oberschelp, Anneli Richter +4
Topological defects provide a unifying language to describe how orientational order breaks down in active and living matter. Considering cells as elongated particles confluent, epi…

Surface Minkowski tensors to characterize shapes on curved surfaces
Lea Happel, Hanne Hardering, Simon Praetorius +1
We introduce surface Minkowski tensors to characterize rotational symmetries of shapes embedded in curved surfaces. The definition is based on a modified vector transport of the sh…

Coordinated motion of epithelial layers on curved surfaces
Lea Happel, Axel Voigt
Coordinated cellular movements are key processes in tissue morphogenesis. Using a cell-based modeling approach we study the dynamics of epithelial layers lining surfaces with const…
