Hopf Algebraic Structure for Tagged Graphs and Topological Recursion

24 Sep 2017  ·  Ding Xiang-Mao, Li Yuping, Meng Lingxian ·

Using the shuffle structure of the graphs, we introduce a new kind of the Hopf algebraic structure for tagged graphs with, or without loops. Like a quantum group structure, its product is non-commutative... With the help of the Hopf algebraic structure, after taking account symmetry of the tagged graphs, we reconstruct the topological recursion on spectral curves proposed by B. Eynard and N. Orantin, which includes the one-loop equations of various matrix integrals as special cases. read more
