摘要：

We present the dynamics of overdamped Brownian self-propelled particles moving on the surface of a sphere. The effect of self-propulsion on the diffusion of these particles is elucidated by determining their angular (azimuthal and polar) mean-square displacement. Short-and long-times analytical expressions for their angular mean-square displacement are offered. Finally, the particles' steadymarginal angular probability density functions are also elucidated.
