How brownian motion occurs
WebThe multifractional Brownian motion is a locally dependent Gaussian nonstationary process, whose flexibility in describing complex phenomena justifies its use in financial dynamics modeling. Assuming it as a model of stock indexes, we estimate the pointwise regularity function for the Dow Jones Ind. Avg., the Footsie 100 and the Nikkei 225.

So the covariance between two time-instances of Brownian motion is. Cov ( B s, B t) = min ( s, t). This post gives a derivation of this fact, but I'm lacking intuition. Suppose ϵ ≪ 1 is small and t is larger. Then. Cov ( B ϵ, B t) = ϵ, Cov ( B t + ϵ, B 2 t) = t + ϵ. In both cases the time step is t − ϵ, but the covariances are ...

WebBrownian MotionBrownian motion (named after the Scottish botanist Robert Brown) or pedesis is the seemingly random movement of particles suspended in a fluid... WebWith regard to Brownian motion, it is a martingale, with respect to the Levi-Civita connection. Being a martingale is not a coordinate-invariant property, (because of Itô's rule, roughly), therefore we cannot say that anything is a martingale, before giving an additional structure to the manifold, namely an affine connection. $\endgroup$
