Random Evolutions
This article gives a short presentation of random evolutions. At first, the following two examples are presented: dynamical stochastic systems and increment processes both in Markov media. After, an introduction to semi-Markov Random evolution in a Banach space is given, where the previous evolutionary systems are obtained as particular cases. Finally, two abstract limit theorems of average and...
متن کاملSpatially Homogeneous String Cosmologies
We determine the most general form of the antisymmetric H-field tensor that is admitted by all possible spatially homogeneous cosmological models in 3+1dimensional low-energy bosonic string theory. The maximum number of components of the H field that are left arbitrary is found for each homogeneous cosmology defined by the Bianchi group classification. The relative generality of these string co...
متن کاملSpatially Homogeneous Dynamic Textures
We address the problem of modeling the spatial and temporal second-order statistics of video sequences that exhibit both spatial and temporal regularity, intended in a statistical sense. We model such sequences as dynamic multiscale autoregressive models, and introduce an efficient algorithm to learn the model parameters. We then show how the model can be used to synthesize novel sequences that...
متن کاملRandom Evolutions toward Applica- Tions
This article gives a short and elementary presentation of random evolutions toward applications in reliability and quality engineering. At first, the following two examples are presented: dynamical stochastic systems and increment processes both in Markov media. A dynamical system in continuous time is presented since nowadays they are widely used in dynamic reliability modeling. Limit theorems...
متن کاملRemarks on Random Evolutions in Hamiltonian Representation
Time evolution of random processes differs in one essential respect from evolution of conservative systems in general and Hamiltonian systems in particular. As a great number of various limit theorems attest, the final states loose all the information about the initial conditions. Thus, there is nothing to be conserved, no constants of motion can exist, and no use can be made of the powerful ma...
