STABILITY OF PERIODIC PLANE-WAVE SOLUTIONS OF WAVE-EQUATIONS

[摘要] Nonlinear wave equations with explicit periodic plane wave solutions are considered. The variational equations governing linear stability are derived and solved. The analysis is applied to the special cases of lambda-PHI4- and Sine-Gordon wave equations.
