Racah operators for unitary representations of groups
R. S. Ismagilov Bauman Moscow State Technical University, 2 Baumanskaya ul. 5, Moscow 107005, Russia
Abstract:
We define Racah operators for unitary representations of groups as a modification of classical Racah coefficients. These operators are explicitly calculated in the case of the motion group of four-dimensional Euclidean space. It turns out that they are related to the geometry of $4$-gons in this space.
Key words and phrases:
groups, representations, Racah operators, quadruples.
