摘要

Continuous stochastic processes are introduced through the Chapman-Kolmogorov equation and then the Fokker-Planck equation. The role of barriers and thus the concept of exit time are discussed. Finally, stochastic differential equations and Ito’s formula are introduced, illustrated with some examples, and the mechanism of stochastic resonance is discussed in detail.
