The condition is named after the Swedish mathematician Lars Hörmander For partial di erential equations the corresponding representation is u(x) = Z P(˘)=0 ei(x;˘) (d˘); (2) where is an arbitrary distribution from a certain class. In particular, is the measure if the roots of P(˘) are simple (L.

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.

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.
