PIMS workshop on New Trends in Localized Patterns in PDEs: Mathematical Theory and Applications to Physics, Biology and the Social Sciences- a Conference in Honour of the 60th Birthday of Michael J. Ward.


Localized spatial-temporal patterns commonly occur for various classes of linear and nonlinear diffusive processes. In recent years, we have witnessed an explosion of many new and exciting developments in the theory and applications of localized solutions in PDEs. Many new frontiers have opened while new connections between old fields have been discovered.


This workshop will highlight Prof.Ward's influential contributions to the mathematics and applications of localized solutions to PDEs. It brings together his students, colleagues and collaborators in a celebration of Prof.Ward's 60th birthday. Over his long career, Prof. Ward has made numerous invaluable contributions to many areas of applied mathematics, including fluid dynamics, metastability, reaction-diffusion equations, cell biology and pattern formation.

 Consider an algebraic group G acting on an irreducible variety X. We say there exists a generic stabilizer for this action if there exists a nonempty open subset Y of X such that the stabilizers of any y in Y are all conjugate in G. In characteristic 0, there are general results of Richardson proving the existence of a generic stabilizer in many cases. We especially consider the case that G is a simple algebraic group in positive characteristic and X is an irreducible G-module. We show that a generic stabilizer always exists and determine the generic stabilizer in all cases. This fails for semisimple groups. This is joint work with Skip Garibaldi and Ross Lawther.
