报告摘要:

In this talk we consider circle patterns from the viewpoint of configurations. By using the topological degree theory, we extend the Koebe-Andreev-Thurston Theorem to include circle patterns with obtuse exterior intersection angles. As a consequence, we obtain a generalization of Andreev's Theorem which allows obtuse dihedral angles.
