Irreducible decompositions of physical tensors of high orders. (English) Zbl 0969.74009

Summary: We use the term ‘physical tensor’ for a tensor that belongs to a tensor subspace. Based on the relationship among the characters of rotation representation, some techniques are developed in order to give the numbers of independent deviatoric tensors contained in irreducible decompositions of physical tensors, even prior to the constructions of irreducible decompositions. Some examples are shown, and many of them are new results.
