Abstract

In the present article a classification of four-dimensional symmetry subalgebras of a d'Alembert equation containing a single second-order operator and satisfying the condition of noncommutative integration is presented. Exact integration is performed by means of these subalgebras and by means of the method of complete separation of variables.
