Title: Motion of a pulse for mass conserved reaction-diffusion systems related to cell polarity

Abstract: We consider mass conserved reaction-diffusion systems on a one dimensional circle and derive the motion of a pulse on it when a small heterogeneity is added. This model is related to cell polarity problems and a heterogeneity corresponds to an external stimulation. Then the motion toward a peak location of the stimulation is theoretically shown as an application.
