www.stat.uchicago.edustochastic 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.

physics.gu.seThe property (6.8) imply that ˘(t) is a wildly uctuating function, and it is not at all obvious that the di erential equation (6.3) has a unique solution for a given initial condition, or even that dv=dtexists. There is a standard existence theorem for di erential equations which guarantee the existence of a local solution if ˘(t) is continous.

Experiment tells us that after su ciently long time they will be in equilibrium with each other. Then they are said to have the same temperature. If for example system Ais in equilibrium with system ...
