Abstract: Many of the recent developments in the theory of optimal stopping have

American put option with solving an optimal stopping problem, as the optimal
stopping time is the rational time for the purchaser to exercise the
option. In this talk I survey some methods used in solving optimal
stopping problems, as motivated by pricing the perpetual American put
