Abstract:
Stopping a process in its midst -- only to start it all over
again -- may prolong, leave unchanged, or even shorten the time
taken for its completion. Among these three possibilities the latter
is particularly interesting as it suggests that restart can be used to
expedite the completion of complex processes which otherwise would
hinder. I will introduce the problem of first passage under restart
using the example of simple diffusion, but will then explain why many
unknowns compel us to generalize to arbitrary first passage processes
and restart mechanisms. Finally, I will demonstrate how the framework
developed herein can serve as a platform to understand bio-chemical reactions
and generic search processes.
