Conditional Law and Occupation Times of Two-Sided Sticky Brownian Motion
Bugra Can, Mine Caglar · 2019-10-23 · via math.PR updates on arXiv.org

Sticky Brownian motion on the real line can be obtained as a weak solution of a system of stochastic differential equations. We find the conditional distribution of the process given the driving Brownian motion, both at an independent exponential time and at a fixed time t>0. As a classical problem, we find the distribution of the occupation times of a half-line, and at 0, which is the sticky point for the process.
