On the Construction and Classification of Common Invariant Solutions for the (1+3)-Dimensional Euler–Lagrange–Born–Infeld Equations and Homogeneous Monge–Ampère Equations
摘要
We study the problem of construction and classifying of common invariant solutions for the (1+3)-dimensional Euler–Lagrange–Born–Infeld and homogeneous Monge–Ampère equations. Some common invariant solutions of these equations obtained from the invariant solutions of the Euler–Lagrange–Born–Infeld equation and the classification of low-dimensional (dimL ≤ 3) nonconjugate subalgebras of the Lie algebra of the Poincaré group P(1,4) are presented and classified.
