Abstract

Symmetry properties of the causal (hyperbolic) heat equations are studied. Symmetry groups of two variants of hyperbolic equations are calculated. The results obtained are analysed and compared with known properties of the classical heat equation. These findings may be considered as possible arguments in favour of one of the causal heat conduction models.
