¿Qué es Markov process, strong Markov property?

También llamado: Markov process · strong Markov property

Definition 2.4 Quantitative Methods · Capítulo 2 — Brownian Motion

An adapted process (Xt)(X_t) is a Markov process if for all s,t≥0s, t \ge 0 and bounded measurable ff, E[f(Xs+t)∣Fs]=E[f(Xs+t)∣Xs]\E[f(X_{s+t}) \mid \mathcal F_s] = \E[f(X_{s+t}) \mid X_s]: given the present, the past adds nothing. It has the strong Markov property if the same holds with ss replaced by any finite stopping time τ\tau.
