## Fourier Analysis. Partial Differential Equations (PDEs)

Fourier Analysis This chapter on Fourier analysis covers three broad areas: Fourier series in Secs. 11.1-11.4, more general orthonormal series called Sturm-Liouville expansions in Secs. 11.5 and 11.6 and Fourier integrals and transforms in Secs. 11.7-11.9. The central starting point of Fourier analysis is Fourier series. They are infinite ...
