五、摘要

Circle packings are configurations of circles with specified patterns and have found both theoretical and practical applications in a wide variety of venues such as complex analysis, computational geometry and combinatorics. In this talk I will give a survey on some nonlinear methods in circle packing theory. These include continuity method, variational principle, topological degree theory and intersection number technique. I will explain how these methods can be applied to studying Koebe-Andreev-Thurson theorem, Midscribability theorem and their generalizations.
