The section also places the scope of studies in APM346 within the vast universe of mathematics. 1.1.1 What is a PDE? A partial di erential equation (PDE) is an equation involving partial deriva-tives. This is not so informative so let’s break it down a bit.

The characteristic equations are dx dt = a(x,y,z), dy dt = b(x,y,z), dz dt = c(x,y,z From Wikipedia, the free encyclopedia In mathematics, Hörmander's condition is a property of vector fields that, if satisfied, has many useful consequences in the theory of partial and stochastic differential equations.

One should note that the stochastic partial differential equation originated from nonlinear filtering problems.

This note is self-contained. The only things we need here are certain prop- erties of the solutions.
