Abstract
We give an exact relationship between the susceptibility and correlation length (which includes the crossover to classical behavior) in a differential renormalization-group approach. We calculate the relationship explicitly for arbitrary-order- Lifshitz systems to leading order. Global scaling properties of the -point Green's functions are given in the differential framework.
