Generalized symmetry and Neumann’s principle

  • S. Bhagavantam
  • P. V. Pantulu


Neumann’s principle is examined in the context of the recent generalizations relating to symmetry and physical properties of crystals. It is shown that the difficulties encountered in applying the principle to transport properties are only apparent and that it is not necessary to impose restrictions on the principle. A proper interpretation of the symmetry of crystals resolves the difficulties and brings out clearly the axiomatic nature of this principle and its universal applicability.
