Simple Lie algebras and topological ODEs

Marco Bertola, Boris Dubrovin, Di Yang

For a simple Lie algebra $g$ we define a system of linear ODEs with polynomial coefficients, which we call the topological equation of $g$ -type. The dimension o…

Correlation functions of the KdV hierarchy and applications to intersection numbers over $M_{g, n}$

Marco Bertola, Boris Dubrovin, Di Yang

We derive an explicit generating function of correlations functions of an arbitrary tau-function of the KdV hierarchy. In particular applications, our formulation gives closed form…

Geometric interpretation of Zhou's explicit formula for the Witten-Kontsevich tau function

Ferenc Balogh, Di Yang

Based on the work of Itzykson and Zuber on Kontsevich's integrals, we give a geometric interpretation and a simple proof of Zhou's explicit formula for the Witten-Kontsevich tau fu…
