How do we determine the units used in a differential equation? Yes, in theory a PDE has nothing to do with units, but I'm interested in this question from a modeling point of view. By units, I mean the following. In an ordinary differential equation, finding the correct units seems relative straightforward.

Lars Valter Hörmander was a Swedish mathematician who has been called "the to the modern theory of linear partial differential equations".

In 1962 he was awarded the Fields Medal for his contributions to the general theory of linear partial differential operators. PARTIAL DIFFERENTIAL EQUATIONS 3 For example, if we assume the distribution is steady-state, i.e., not changing with time, then ∂w = 0 (steady-state condition) ∂t and the two-dimensional heat equation would turn into the two-dimensional Laplace equa tion (1).

Included are most of the standard topics in 1st and 2nd order differential equations, Laplace transforms, systems of differential eqauations, series solutions as well as a brief introduction to boundary value problems, Fourier series and partial differntial equations. This graduate-level course is an advanced introduction to applications and theory of numerical methods for solution of differential equations.
