An introduction to general theory of two-parameter processes that has developed since around 1975. It presents results of research by the author on martingale theory and stochastic calculus for two-parameter processes. It is suitable for those who are interested in the theory of two-parameter processes and basics of their stochastic calculus.

A collection of articles written by mathematicians and physicists, designed to describe the state of the art in climate models with stochastic input. Mathematicians will benefit from a survey of simple models, while physicists will encounter mathematically relevant techniques at work.

Stochastic resonance is a phenomenon arising in a wide spectrum of areas in the sciences ranging from physics through neuroscience to chemistry and biology.
This book presents a mathematical approach to stochastic resonance which is based on a large deviations principle (LDP) for randomly perturbed dynamical systems with a weak inhomogeneity given by an exogenous periodicity of small frequency. Resonance, the optimal tuning between period length and noise amplitude, is explained by optimising the LDP's rate function.
The authors show that not all physical measures of tuning quality...
