Let $B(t)$ be a Brownian motion in $R^3$. A {it subpath} of the Brownian path $B[0,1]$ is a continuous curve $gamma(t)$, where $gamma[0,1] subseteq B[0,1]$ , $gamma(0) = B(0)$, and $gamma(1) = B(1)$. ...
Variably Skewed Brownian Motion
Skew Brownian motion Brownian motion stochastic differential equation local time

Given a standard Brownian motion $B$, we show that the equation
X_t = x_0 + B_t + beta(L_t^X), t geq 0,
has a unique strong solution $X$. Here $L^X$ is the symmetric local time of $X$ at $0$, and ...
Equidistant sampling for the maximum of a Brownian motion with drift on a finite horizon

A Brownian motion observed at equidistant sampling points renders a random walk with normally distributed increments. For the difference between the expected maximum of the Brownian mo- tion and its s...

We give a new representation of fractional Brownian motion with Hurst parameter $Hleqfrac{1}{2}$ using stochastic partial differential equations. This representation allows us to use the Markov proper...
We define a Fractional Brownian Motion indexed by a sphere, or more generally by a compact rank one symmetric space, and prove that it exists if, and only if, 0< H leq 1/2. We then prove that Fraction...

Let B be a standard Brownian motion and let b_gamma be a piecewise linear continuous boundary function. In this paper we obtain an exact asymptotic expansion of P{ B(t)< b_gamma(t), forall tin [0,1]} ...
An Extreme-Value Analysis of the LIL for Brownian Motion
The law of the iterated logarithm Brownian motion extreme values
2009/4/27
We use excursion theory and the ergodic theorem to present an extreme-value analysis of the classical law of the iterated logarithm (LIL) for Brownian motion. A simplified version of our method also p...
