Nowhere differentiable
Web3. Brownian Motion is Nowhere Differentiable Even though Brownian motion is everywhere continuous, the randomness allows Brownian motion to also be nowhere di erentiable. Lemma 3.1. (Scaling Invariance). Suppose fB(t) : t 0gis a standard Brownian motion and let a>0. Then the process fX(t) : t 0gde ned by X(t) = 1 a B(a2t) is also a standard ... WebThere are many examples of "non-random" curves that are continuous everywhere, and yet differentiable nowhere. For example, the one defined by the formula f ( x) = ∑ k = 0 ∞ 2 − k cos ( 2 k x). You may think of it as a limit of partial sums f n ( x) = ∑ k = 0 n 2 − k cos ( 2 k x).

WebContinuous Nowhere Differentiable Functions - Feb 06 2024 This book covers the construction, analysis, and theory of continuous nowhere differentiable functions, comprehensively and accessibly. After illuminating the significance of the subject through an overview of its history, the reader WebThe proof of nowhere differentiability relies on constructing a sequence δm such that as δm the value of the derivative quotient, , blows up proving that the function can’t be differentiable at any x. The construction and proof of the blow up is technical so just bear with it, it ends up giving us the answer we need. Proof.

Web8 okt. 2009 · Nowhere differentiable. Although it is continuous, the sample paths of Brownian motion are nowhere differentiable. Historically, the first published example of a continuous but nowhere differentiable function was the Weierstrass function, in 1872.In fact, at a cursory glance, it does look very similar to Brownian motion.
