The first-passage area of Wiener process with stochastic resetting

Abstract

For a one-dimensional Wiener process with stochastic resetting $\mathcal{X}(t)$, obtained from an underlying Wiener process $X(t),$ we study the statistical properties of its first-passage time through zero, when starting from $x>0,$ and its first-passage area, that is the random area enclosed between the time axis and the path of the process $\mathcal{X}(t)$ up to the first-passage time through zero. By making use of solutions of certain associated ODEs, we are able to find explicit expressions for the Laplace transforms of the first-passage time and the first-passage area, and their single and joint moments.
