Infinite-dimensional symmetry for wave equation with additional condition
arXiv:0910.2380
Abstract
Symmetries for wave equation with additional conditions are found. Some conditions yield infinite-dimensional symmetry algebra for the nonlinear equation. Ansatzes and solutions corresponding to the new symmetries were constructed.
