On the symmetry structure of the minimal surface equation
arXiv:math/0410557
Abstract
An infinite sequence of commuting nonpolynomial contact symmetries of the two-dimensional minimal surface equation is constructed. Local and nonlocal conservation laws for -dimensional minimal area surface equation are obtained by using the Noether identity.
