A geometric theory for scroll wave filaments in anisotropic excitable media. (English) Zbl 1185.37187
The authors study some models arising in the theory of scroll wave filaments in anisotropic excitable media. The model is presented by a nonlinear reaction-diffusion equation. Firstly, the authors explain the origin of the model and give an interesting overview on the works that have been done previously for the model. The authors provide also several properties of curved spaces. Some numerical simulations are provided to explain the phenomena.
