We consider finite temperature dynamical correlation functions in the
interacting delta-function Bose gas. In the low-temperature limit the
asymptotic behaviour of correlation functions can be determined from c
onformal field theory. In the present work we determine the deviations
from conformal behaviour at low temperatures.
