On edge interactions and surface tension
The authors aim at bringing into the open the systems of forces that give rise to distributions of forces over edges. It is their crucial interest to have a precise definition that does not exclude ``cusped'' edges. The contact of surfaces and regions is defined in the third chapter, while contact interactions are outlined in chapter four. After ``an intermezzo on wedge interactions'' chapter five illustrates various essential contacts. Resultant actions in chapter six which might be ``quasi- balanced'' in chapter seven are enriched by boundary conditions in chapter eight. Examples, namely on surface tension, are presented in chapter nine. The authors require new extended concepts from geometric measure theory.
