stochastic di erential equations (2). Are there always solutions to stochastic di erential equations of the form (1)? No! In fact, existence of solutions for all time t 0 is not guaranteed even for ordinary di erential equations (that is, di erential equations with no random terms). It is important to understand why this is so.

Equations (1, 3, 4) generalize to the stochastic case in the same way as equation (2) does. An optimal control problem with discrete states and actions and probabilistic state ... Consider the stochastic di⁄erential equation dx = f (x;u)dt+F (x;u)dw (6) where dw is n w-dimensional Brownian motion. This is sometimes called a controlled Ito
