A numerical study of analyticity in the coupling constant
For two simple field theories both of zero-space dimension, the Riemann surface of the energy as a function of the square of the coupling constant is studied. The convergence of perturbation theory is established and comparison is made between the exact energies and their Pade approximations. (18 re...
