The Core of the Spiral

SIAM Journal on Applied Mathematics, 1992
Summary: The problem of finding the unique frequency and shape, including the core, of spirals in excitable media is studied. A leading-order approximation of the problem is formulated as a nonlinear eigenvalue problem involving only ordinary differential equations.

Meandering Spirals

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1999
AbstractSpiral wave patterns in chemical reactions and their dynamics have received a lot of interest in the past few years, from the experimental and from the theoretical side. We review some of the recent mathematical results addressing a bifurcation theoretic approach to meandering and drifting tip motions.
