Abstract
In this talk, we show the second order Boltzmann equation with polarisation without specifying any gauges. In order to describe a polarisation of photon, we introduce a tensor-valued distribution function. We derive the gauge transformation rules for metric, momentum and distribution function. We correct the previous results for gauge transformtion rule of distribution function in which some terms were missed. The tensor-valued distribution function is a tensor on two dimensional polarisation surface, therefore, we have to consider the change of polarisation surface as well as its transformation rules as a tensorial quantity in the gauge transformation. For a consistency, we check the gauge invariance of the derived equation. Finally, we give a short comment on the observed temperature.
