Let X = (Xi)i∈Z, where Xi ∈ X and X is a (measurable) state space, be a stochastic process. The thesis is focused on the role played by the return time process R = (Ri)i∈Z of consecutive return times of X to some prescribed ...

Spring systems are commonly employed to model properties of real physical objects. They are frequently used to illustrate how a solid or a microscopic body distorts under the influence of external forces. The aim of this ...
