Abstract The effects of aberration, retardation and magnetic field sweep back, which are caused directly or indirectly by pulsar’s rapid rotation, are estimated in order to examine their influences on the geometry asymmetry of the mean pulse profile. The geometric asymmetry exhibits different behaviors at different cases. The millisecond pulsars incline to develop mean pulse profiles with asymmetric contrary to the normal pulsars. The pulsar J0437-4715 is analyzed as an example.
