Today we have an opportunity to meet our friends working on the algebro-geometry, the symplectic geometry, and some topological string theory:
Here Bertrand Eynard (Saclay) a little informally introduced some historical aspects of matrix models of Kontsevich-Witten and Mulase was more on the algebraic geometry of the characteristic classes of Hodge bundles on the Deligne-Mumford compactification of stable maps.
We also heard the talk of Akaho on the immersion version of Floer theory of Fukaya category of $A_{\infty}$-algebra structure, which look alike the intersecting branes of recent topological string theory (of A-model by FOOO (2008)).
