Geophysical Monge–Ampère-Type Equation: Symmetries and Exact Solutions
- Andrei D. Polyanin and
- Alexander V. Aksenov
This paper studies a mixed PDE containing the second time derivative and a quadratic nonlinearity of the Monge–Ampère type in two spatial variables, which is encountered in geophysical fluid dynamics. The Lie group symmetry analysis of t...
