A criterion will be presented for the log-Sobolev inequality for unbounded
spin systems on the lattice with non-quadratic interactions. This is a
joint work with Takis Konstantopoulos (Uppsala) and James Inglis (INRIA).
Furthermore, in the case of quadratic interactions, a perturbation result
for the inequality will be presented.
