Abstract
The spin, charge and pairing correlation functions for the ground state of two-dimensional model are calculated by using the power method which projects out the ground state from a variational wave function. ``Exact'' results are obtained for and lattices with low particle densities. The results are surprisingly similar to that of one-dimensional model. The phenomenology is almost perfectly correlated with the concept of Tomonaga-Luttinger liquid and it is incompatible with traditional Fermi liquid theory.
