Workshop on Wave Breaking and Global Solutions in the Short-Pulse Dispersive Equations
at the Fields Institute , 222 College Street, Toronto

Organizer: Dmitry Pelinovsky, McMaster University (Canada)


The scientific importance of very short pulses originates from applications for high power lasers and MHD/fusion devices such as Tokamaks. The classical envelope equations (such as the nonlinear Schrodinger equation) are no longer valid as the pulse width is only few carrier wavelengths, instead of thousands of these. The short-pulse equation was derived in this context as the alternative of the nonlinear Schrodinger equation to describe ultra-short pulses with fewer cycles. This equation represents the class of nonlinear dispersive wave equations with low-frequency dispersion, which reduce in the dispersionless limit to the invisid Burgers equation. Another famous member of this class is the reduced Ostrovsky equation derived in the context of surface water waves in a rotating fluid.

The five-day workshop will focus on the open problems in the wave breaking and the existence of global solutions for the short-pulse and other nonlinear dispersive wave equations. This workshop will also initiate collaborations between applied mathematicians, who are involved with the actual modeling of dispersive wave equations, and more pure analysts, who are interested in the analytic solutions of these equations.
