Pfaffianization of a semi-discrete KP equation and matrix integrals

Wen-Xiu Ma

Abstract

In this talk, I'd like to first explore a semi-discrete KP equation whose solutions can be expressed in terms of both Wronskian determinants and Grammian determinants. Through the procedure of Pfaffianization, we are able to derive the coupled system for the semi-discrete KP equation. Due to the close connections between matrix integrals and integrable systems, we manage to obtain matrix integral solutions to the semi-discrete KP equation and its coupled system.

Inversible fibrations, globalization and triviality of maps

Abstract

Dyer and Eilenberg (1988) in “Globalizing Fibrations by schedules” defined inversible fibration and prove a globalization theorem for these kind of fibrations, then they asked whether a locally trivial maps over contractible space is trivial. In this talk, we provide some further details concerning inversible fibrations and we define also inversible Hurewicz Fibrations, relate these to the inversible fibrations of Dyer and Eilenberg and study inversibility for path space fibrations. An affirmative answer to a special case of the Dyer and Eilenberg question is given.
