"Pseudodifferential operators, optimal grids, and evolution equations: a
case study for micromagnetics"

Abstract:
Pseudodifferential operators, such as the Dirichlet-to-Neumann map for
the Laplace's equation in half-space often arise in nonlinear
problems, and, in particular, in the context of pattern
formation. Efficient numerical methods can therefore be very useful in
understanding the spatiotemporal dynamics in these complex nonlinear
systems. In this talk, I will review a number of examples of models in
developmental biology, semiconductors physics, and micromagnetics in
which pseudodifferential operators play a crucial role. I will then
discuss several implementations of optimal grids for the numerical
studies of the domain wall structures in thin film micromagnetics and
present an important new type of solutions found in these studies.
