Mean of brownian motion

Brownian motion, or pedesis (from Ancient Greek: πήδησις /pɛ̌ːdɛːsis/ "leaping"), is the random motion of particles suspended in a medium (a liquid or a gas).

WebApr 23, 2024 · In the most common formulation, the Brownian bridge process is obtained by taking a standard Brownian motion process X, restricted to the interval [0, 1], and conditioning on the event that X1 = 0. Since X0 = 0 also, the process is tied down at both ends, and so the process in between forms a bridge (albeit a very jagged one). WebFeb 23, 2015 · Essentially, Brownian motion is a measure on the space of continuos functions (trajectories), say on an interval on the real line . How does one describe this measure in probabilistic terms? One sets the probability space (Ω, P) and a measurable function from it to the target space: F: Ω → C[0, 1]
