    "abstract": "We present a non-perturbative method for the study of the O(N+1)-version of\nthe linear sigma-model. Using boson-mapping techniques, in close analogy to\nthose well-known for fermionic systems, we obtain a systematic 1/N-expansion\nfor the Hamiltonian which is symmetry-conserving order by order. The leading\norder for the Hamiltonian is evaluated explicitly and we apply the method to\n$\\pi\\pi$-scattering, in deriving the T-matrix to leading order.",
