Renormalization group approach to the interacting bose fluid

It is pointed out that the method of functional integration provides a very convenient starting point for the renormalization group approach to the interacting Bose gas. Using such methods we show in a general and non-perturbative way that the critical exponents of the Bose gas are identical to those of a classical system of spins with two real components.
