Tensorial Classification Of Domain Pairs

A classification of domain pairs via a group theoretical classification of the corresponding pairs of a full physical property tensor characterizing the domains has been introduced by V. Janovec (Czech. J.Phys., B22, 974 (1972)). This classification scheme is extended here from the case of fd physical property tensors, where each domain is characterized by a unique form of the physical property tensor, to the case of parrial physical property tensors, where more than a single domain is characterized by a specific form of the physical property tensor.
