Abstract
The dynamics of chemical spiral waves in an excitable reaction-diffusion system on a sphere is numerically investigated by employing a spectral method using spherical harmonics as basis functions. A nearly antisymmetric spiral wave is produced even from a symmetric spiral wave in the presence of a little inhomogeneity of the medium. In a homogeneous medium, the tip of the nearly antisymmetric spiral wave at the source rotates steadily, but the other tip changes its shape in an almost periodic manner.
