Invariants, Lie-Bäcklund operators and Bäcklund transformations
<p>This thesis is mainly concerned with the application of groups of transformations to differential equations and in particular with the connection between the group structure of a given equation and the existence of exact solutions and conservation laws. In this respect the Lie-Bäcklund...
