Abstract
Shows how for classical canonical transformations the authors can pass, with the help of Wigner distribution functions, from their representation U in the configurational Hilbert space to a kernel K in phase space. The latter is a much more transparent way of looking at representations of canonical transformations, as the classical limit is reached when h(cross) to 0 and the successive quantum corrections are related with the power of h(cross)2n, n=1,2, et seq.Keywords
