Course description and aims
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.
Student learning outcomes
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.
Keywords
Hilbert space, orthonormal basis, Bessel's inequality, Parseval's identity, Fourier transform, Riemann-Lebesgue lemma, Fourier inversion formula
Competencies that will be developed
| ✔ Specialist skills | Intercultural skills | Communication skills | Critical thinking skills | Practical and/or problem-solving skills |
Class flow
Before coming to class, students should read the course schedule and check what topics will be covered.
Required learning should be completed outside of the classroom for preparation and review purposes.

Out-of-Class Study Time (Preparation and Review)
To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.
