Abstract
Semiboundedness of the total Hamiltonian is proved for a selfinteracting Boson field in two dimensional space time. The interaction is given by a Wick polynomial:P(Φ):. The polynomial P is required to have even degree and its leading coefficient must be positive. A space cutoff is introduced in the interaction Hamiltonian.
