Generating relations for reducing matrices. III. Kronecker products
Rainer Dirl, Peter Kasperkovitz, Mois Ilia Aroyo, J. N. Kotzev, Brian Davies · Journal of Mathematical Physics · 1987
In the first two of this series of papers [R. Dirl et al., J. Math. Phys. 27, 37 (1986); M. I. Aroyo et al., ibid. 27, 2236 (1986)] a systematic method to calculate the elements of reducing matrices has been developed. In this paper this ‘‘auxiliary group approach’’ is adapted to multiple Kronecker products. Three examples are worked out to illustrate the efficiency of generating relations and the proposed reduction of the multiplicity problem.
