First-passage statistics of random walks: a general approach via Riemann-Hilbert problems
Mattia Radice, Giampaolo Cristadoro
We study first-passage statistics for one-dimensional random walks with independent and identically distributed jumps starting from the origin. We focus on the joint distribu…

Optimal conditions for first passage of jump processes with resetting
Mattia Radice, Giampaolo Cristadoro, Samudrajit Thapa
We investigate the first passage time beyond a barrier located at of a random walk with independent and identically distributed jumps, starting from . The walk is s…

Optimizing Leapover Lengths of Lévy Flights with Resetting
Mattia Radice, Giampaolo Cristadoro
We consider a one-dimensional search process under stochastic resetting conditions. A target is located at and a searcher, starting from the origin, performs a discrete-ti…
