In particular, solving wave, Laplace and heat equations using Fourier transform. We also introduce the theory of distributions and examine their relation to the Fourier transform, and we then use this methods to nd solutions to linear partial di erential equations. In particular, fundamental solutions to heat operators ienSolving SecondOrder PdesUsing Fourier TransformThesis
