The first half of this course is devoted to study the functional analytic framework of Fourier series.
The second half is devoted to study Fourier transform, which is a continuous counterpart of Fourier series.
In particular, we reconsider Fourier series as an orthonormal basis in a function space, and understand an abstract framework of Fourier series.
Moreover, we study fundamentals of Fourier transform and its applications to differential equations.
Students are expected to understand the functional analytic framework of Fourier series.
Moreover, we aim at understanding fundamentals of Fourier transform, its relation to Fourier series, and applications to differential equations.
Hilbert space, orthonormal basis, Bessel's inequality, Parseval's identity, Fourier transform, Riemann-Lebesgue lemma, Fourier inversion formula
