A new equation describing the bubble expansion in metastable media

The nonlinear Klein–Gordon equation modeling a metastable medium with a small vacuum energy difference ΔU is considered. An equation describing the expansion of a bubble of a large radius  R is obtained in the second approximation in ΔU and 1/ R.
