Abstract:
Numerical computation of pulses and their dynamics
Bjoern Sandstede, Ohio State University
Localized travelling-wave solutions of partial differential equations
on the real line correspond to homoclinic orbits of an associated
ordinary differential equation. Here, we will focus on the numerical
computation of homoclinic orbits and the accurate detection of their
bifurcation points. Super-convergence results for the wave speed are
presented. Finally, we will study the interaction of pulse packets.
These are solutions of the PDE to an initial value which is given by
concatenated, widely separated copies of a primary travelling wave.
The fate of such solutions under truncation of the real line to a finite
interval is investigated.
