A rigoros renormalization group method
We study gradient models on the lattice Z^d with nonconvex interactions. These models serve as effektive model for interfaces. Via a rigourous renormalization group analysis we obtain a representation for the partition function of the finite volume Gibbs measure. The result can be found in [AKM16].
