Abstract
We consider the states of a two-mode light field which are invariant u nder rotation of the coordinate axis. We derive the general form of Wi gner, Q and P functions as well as the density matrix. On imposing fur ther invariances we recover the results for the unpolarized radiation of different kinds.
