摘 要:Koebe-Andreev-Thurston theorem studies the existence and rigidity of circle patterns of a given combinatorial type and the given non-obtuse exterior intersection angles. By using topological degree theory and variational principle, we will derive a series of results generalizing Koebe-Andreev-Thurston theorem to the case of obtuse exterior intersection angles.
