摘要: The angle-angular momentum quantum phase space is considered and the corresponding Heisenberg - Weyl group studied. When (2j+1) a power of prime, Z(2j+1) Galois field stronger results can be proved. SL(2,Z(2j+1)) transformations are explicitly constructed various properties displacement operators Central extensions Abelian by studied they provide all ways constructing from G Z(2j+1).
