## THE GEOMETRY OF FOAMS

Foams are important materials for many practical purposes,
because of their elastic properties, acoustic damping, consistency,
and ability to transport gas. We will consider mathematical models
of soap bubbles, foams and froths, as collections of surfaces which
minimize area under volume constraints. The resulting surfaces
have constant mean curvature, and obey certain combinatorial rules
making them dual to triangulations.
