| Research Abstract |
Some of pattern formation phenomena in nature are described by reaction-diffusion equations. In this research subject, the bistable reaction-diffusion equations describing phase transition is considered, and in particular, its linearized eigenvalue problems associated with stationary layer patterns are analyzed. The relationship between pattern of stationary solutions and those of eigenfunctions is of interest, and asymptotic formulas which provide patterns of most eigenfunctions are proved.
