Resetting or restart is prevalent in natural and engineered systems giving rise to a long series of non-equilibrium phenomena. In this talk, I will discuss two complementary frameworks namely the master equation approach and the renewal approach to treat resetting in a wide array of stochastic systems. Taking advantage of the latter approach, we will show how the solution to the resetting problem can be given in terms of the solution to the original dynamics – which reduces the overall complexity in many folds. In the second part of the talk, I will argue why the theory of instantaneous resetting is a major impediment to practical realization or experimental verification in Brownian systems, and thus a generalization of the existing theory to incorporate non-instantaneous resetting is very much in need. The talk will end with a general overview of treating path-functionals in resetting systems.
