Comments on the strong-coupling calculations and the Pade approximants
Description
The lattice version of the 0(2)σ-model with an abelian gauge interaction is analyzed with the lattice Hamiltonian perturbation (strong coupling regions). To go to the continuum theory the Pade approximants are used. In this model the energy spectrum is calculated and non-existence of a phase transition is proved. (author)
