Markov Processes and Stochastic Calculus

• Ω: An abstract space of points ω ∈ Ω. • F : a σ-field (or σ-algebra) on Ω. That is, a collection of subsets of Ω satisfying: 1. Ω ∈ F . 2. Let A ⊆ Ω such that A ∈ F then Ac = Ω−A ∈ F . 3. Let A1, A2, A3, · · · ∈ F then A1 ∪A2 ∪A3 ∪ · · · ∈ F . The elements of F are called events. Condition (1) above simply states that the space Ω is necessarily an event. Conditions (2) and (3) state that the ...

Stochastic Processes ( Fall 2014 ) Spectral representations and ergodic theorems for stationary stochastic processes Stationary stochastic processes

A stochastic process X is strongly stationary if its fdds are invariant under time shifts, that is, for any (finite) n, for any t0 and for all t1, ..., tn ∈ T , (Xt1 , ..., Xtn) and (Xt1+t0 , ..., Xtn+t0) have the same distribution. A stochastic process X is weakly stationary if its mean function is constant and its covariance function is invariant under time shifts. That is, for all t ∈ T , E(...

On General Perturbations of Symmetric Markov Processes

Let X be a symmetric right process, and let Z = {Zt, t ≥ 0} be a multiplicative functional of X that is the product of a Girsanov transform, a Girsanov transform under time-reversal and a continuous Feynman-Kac transform. In this paper we derive necessary and sufficient conditions for the strong L-continuity of the semigroup {Tt, t ≥ 0} given by Ttf(x) = Ex [Ztf(Xt)], expressed in terms of the ...

On Marginal Markov Processes of Quantum Quadratic Stochastic Processes

In the paper it is defined two marginal Markov processes on von Neumann algebras M and M⊗M, respectively, corresponding to given quantum quadratic stochastic process (q.q.s.p.). It is proved that such marginal processes uniquely determines the q.q.s.p. Moreover, certain ergodic relations between them are established as well.

Stochastic Calculus for Symmetric Markov Processes

Using time-reversal, we introduce a stochastic integral for zero-energy additive functionals of symmetric Markov processes, extending earlier work of S. Nakao. Various properties of such stochastic integrals are discussed and an Itô formula for Dirichlet processes is obtained.
