Abstract: The braking index of a pulsar is expected to be 3 if it slows down under ordinary magnetic dipole radiation . However, measured braking indices of young as well as old pulsars are experimentally determined to be different from the above value. Sometimes these get to large positive and negative numbers. This is something that is not well understood. We will describe pulsar braking index variations based on Relativistic plasma diffusion theory which is currently developed by us. Using this theory we will calculate the braking indices of four-young well known pulsars and two old pulsars. It is also important to establish whether the observed(measured ) braking index riots is time dependent . We will also derive braking indices of three pulsars as a function of time and draw the graphs to show the time evolution of braking index. v
