Welcome to the class website for the course Applied Stochastic Analysis. The class will focus on central topics in the calculus of stochastic processes and on related applications in the natural sciences and engineering. For more details see the syllabus and the topics listed below.

Selection of Topics

• Continuous-time Stochastic Processes
• Stochastic Differential Equations
• Ito's Stochastic Calculus
• Ito Integral, Ito Lemma, Ito Isometry
• Dynkin's Formula
• Girsanov Theorem
