Cluster expansion for P(fi)_{2}: explicit estimates

Rezumat:

We apply the tree expansion to the polynomial self-interacting quantum fields in two dimension. In the range of small coupling constants, we show that the expansion is also convergent when the full propagator is considered and the theory is regularized by normal ordering. Explicit estimates of the convergency ranges are given.
