1.1 PDE motivations and context The aim of this is to introduce and motivate partial di erential equations (PDE). The section also places the scope of studies in APM346 within the vast universe of mathematics. A partial di erential equation (PDE) is an gather involving partial derivatives. This is not so informative so let’s break it down a bit.

Linear PDEs can be reduced to systems of ordinary differential equations by the important technique of separation of variables. This technique rests on a characteristic of solutions to differential equations: if one can find any solution that solves the equation and satisfies the boundary conditions, then it is the solution (this also applies to ODEs). We assume as an ansatzthat the dependence of a solution on the parameters space and time can be written as a produc…

It is generally nontrivial to nd the solution of a PDE, but once the solution is found, it is easy to verify whether the function is indeed a solution. For example to see that u(t;x) = et x solves the wave equation (1.5), simply substitute this function into the equation: (e t x) tt (et x) xx= e et x= 0: 1.1 Classi cation of PDEs
