Abstract
This paper is devoted to a systematic construction of second-order dif ferential equations invariant under the Poincare, sill!similitude and conformal groups in three-dimensional spacetime. A classification of a ll possible realizations of the Lie algebras under the action of the g roup of local diffeomorphisms of R-4 is presented. Then by means of th e differential invariants the most general invariant differential equa tions of second order are constructed.
