摘要：

Some non-Gaussian aspects of chaotic transport are investigated for a general class of two-dimensional area-preserving maps. Kurtosis, in particular, is calculated from the diffusion and the Burnett coefficients, which are obtained analytically. A characteristic timescale delimiting the onset of the Markovian regime for the master equation is established. Some explicit examples are discussed.
