Course description and aims

The functional analysis is a mathematical tool for signal processing, image processing, pattern recognition, and system theory. The course teaches foundations of functional analysis in an easily-understood manner by using various applications. The aim of the course is to capture various mathematical problems in a unified manner, even though they are seemingly different, by using the concept of space, convergence, and operator.

Student learning outcomes

By completing the course, students will be able to
1) Understand the foundations of functional analysis, and apply to various engineering problems.
2) Understand the projection theorem and fixed-point theorem, and explain their meanings.
3) Interpret the least squares approximation problem geometrically.

Keywords

linear space, fixed-point theorem for contraction mapping, Banach space, Hilbert space, linear operator, orthogonal projection theorem, least squares approximation problem, reverse problem, generalized Fourier series

Competencies that will be developed

✔ Specialist skills Intercultural skills Communication skills Critical thinking skills ✔ Practical and/or problem-solving skills
