O. Arratia et Ma. Delolmo, CONTRACTION OF REPRESENTATIONS OF 1+1 KINEMATICAL GROUPS AND QUANTIZATION, International journal of modern physics A, 12(1), 1997, pp. 125-130
We study the contraction from the Poincare to the Galilei group in (11) dimensions. We apply these results to quantize, in the sense of Moy
al, galilean and relativistic elementary systems using the method of t
he Stratonovich-Weyl Correspondence.
