Abstract: | Numerical experiments to the (1 + 1)-dimensional (Ø4?)2 equation are reported. In a certain amplitude region a soliton-antisoliton bound state Ø(x, t >) (pulson) decays much slower than exponentially in time. For 0.30 ? Ø (0, t) ? 1.44 the slope of the maximum amplitudes is found between 0 and ?2 × 10?6 per unit time. In consequence, the lower bound for the pulsons' lifetime can be essentially increased. |
