报告摘要：Compressible Euler equations with Coriolis force are the fundamental model in the study of atmospheric dynamics. In this article, we study the lifespan of the projected 2-dimensional C^2 non-vacuum solutions of the compressible Euler equations with Coriolis force. We _rst locate the vortex equations for the compressible Euler equations with Coriolis force and then use the integration method to prove that the corresponding blowup results exist for the rotational C^2.

报告摘要：We have investigated solutions of the KMM system in two cases for s=0 and s≠0) by the CTE method and the Painlevé-Bācklund transformation, for the case(s=0), the KMM system is integrable. There are many new type structures of solutions obtained., such as breather soliton, multipole instanton and rogue waves. Rogue waves have different structures including butterfly-type, X-type and Y-type ones. We also study in details the effects of Gilbert-damping and inhomogeneous exchange on the propagation of short waves in various saturated garnet ferrites.

报告摘要：Recently, Hone, Novikov and Wang have given a list of generalized short pulse equations which are integrable. Among them, three are related to the 3-reductions of BKP/CKP hierarchies. In this talk, we will focus on two generalized short pulse (gSP) equations which are not known until Hone et al.'s work. We will construct their integrable semi-discretizations based on their connections of 3-reduction of negative BKP/CKP hierarchies.
