Discrete Topology-Revealing Vector Fields on Simplicial Surfaces with Boundary

  title={Discrete Topology-Revealing Vector Fields on Simplicial Surfaces with Boundary},
  author={Konstantin Poelke and K. Polthier},
We present a discrete Hodge-Morrey-Friedrichs decomposition for piecewise constant vector fields on simplicial surfaces with boundary which is structurally consistent with the smooth theory. In particular, it preserves a deep linkage between metric properties of the spaces of harmonic Dirichlet and Neumann fields and the topology of the underlying geometry, which reveals itself as a discrete de Rham theorem and a certain angle between Dirichlet and Neumann fields. We illustrate and discuss this… CONTINUE READING
