L643-L648, 2004.0305-4470http://hdl.handle.net/11449/23149A Wigner function associated with the Rogers-Szego polynomials is proposed and its properties are discussed. It is shown that from such a Wigner function it is possible to obtain well-behaved probability distribution functions for both angle and action variables, defined on the compact support -pi less than or equal to theta < pi, and for m greater than or equal to 0, respectively. The width of the angle probability density is governed by the free parameter q characterizing the polynomials.L643-L648engArtigo10.1088/0305-4470/37/50/L01WOS:000226014400002Acesso restrito
