Federbush, Paul Partially alternate derivation of a result of Nelson. (English) Zbl 0165.58301 J. Math. Phys. 10, 50-52 (1969). Summary: The result of E. Nelson [ “A quartic interaction in two dimensions” in: Proc. Conf. Math. Theory Element. Particles, Dedham, Mass. 1965, 69–73 (1965)] that the total Hamiltonian is semibounded for a self-interacting Boson field in two dimensions in a periodic box is derived by an alternate method. It is more elementary in so far as functional integration is not used.
