Generalized KMT conjecture for Delaunay circle patterns
Generalized KMT conjecture for Delaunay circle patterns
Let be a closed, oriented surface of genus at least . An admissible weighted graph in is a graph embedded in that is the 1-skeleton of a cell decomposition, with such that the sum of the edge weights around every face is , while the sum around every contractible cycle not contained in the boundary of a face is strictly greater than . Let be the space of pairs consisting of a complex projective structure on and a circle pattern with nerve and intersection angles . Generalized KMT conjecture. For every admissible weighted graph , the forgetful map
is a homeomorphism. This generalizes the circle-packing statement to Delaunay circle patterns with prescribed intersection angles. The conjecture has been proved for tori by Wayne Lam; the supplied source does not assert a result for the stated genus-at-least-two setting.
