报告摘要: In this talk we will investigate circle patterns from the viewpoint of configurations. By using the topological degree theory, we extends  Koebe-Andreev-Thurston Theorem to include circle patterns with obtuse exterior intersection angles. As a consequence, we obtain a generalized Andreev's Theorem which allows obtuse dihedral angles.
