Title


The Combinatorics of Foams


Abstract


Foams, consisting of bubbles separated by interfaces that minimize their surface area, are models for many cellular materials. Plateau's laws show that foams are combinatorially dual to triangulations. Focusing on measures related to average degree, we survey various results on the combinatorics of foams, including a few rigorous mathematical theorems and many physical heuristics.
