Abstract: The intersection theory on moduli space of Riemann surfaces has wide applications to many subjects of mathematics and physics, since the celebrated Witten-Kontsevich theorem (1990) connecting it to matrix integral and integrable system. We will talk about the super version of this intersection theory, which is related to Jackiw-Teitelboim (JT) supergravity, especially their polynomiality, recurision and asymptotics. This is joint work with Prof. K. Liu and my students X. Huang and Y. Zhi.
