    "abstract": "We study the stability of quantum motion of classically regular systems in\npresence of small perturbations. Onthe base of a uniform semiclassical theory\nwe derive the fidelity decay which displays a quite complexbehaviour, from\nGaussian to power law decay $t^{-\\alpha}$ with $1 \\le \\alpha \\le 2$.\nSemiclassical estimates are given for the time scales separating the different\ndecaying regions and numerical results are presented which confirm our\ntheoretical predictions.",
