Period-doubling bifurcations of spiral waves (Venue: MR3 CMS)

Sandstede, B (Surrey)
Tuesday 13 December 2005, 11:30-12:30

Meeting Room 3, CMS


Motivated by experimental observations in light-sensitive Belousov-Zhabotinsky reaction and subsequent numerical work by Kapral, we discuss period-doubling bifurcations of spiral waves. We report on explanations of this phenomenon that involve the computation of spectra, and of the associated eigenfunctions, of spirals on bounded and unbounded domains.
