Abstract
We present three classes of exactly solvable models for fermion and boson s ystems, based on the pairing interaction. These models are solvable in any dimension. As an example we show the first results for fermions interacting with repulsive pairing forces in a two-dimensional square lattice. In spit e of the repulsive pairing force the exact results show attractive pair cor relations.
