Combinatorics and the Rigidity of Frameworks

  title={Combinatorics and the Rigidity of Frameworks},
  author={Brigitte Servatius},
A wide variety of physical structures, e.g. scaffolding (rigid), or a DNA molecule (non-rigid), may be modeled as a collection of rigid rods connected to one another by idealized ball joints. For a given structure, the basic question that arises is whether it is rigid and, if not, how to describe its motion. We would like to describe some of the… CONTINUE READING
