This course teaches complex functions and special functions in mathematics for physics.
Students learn complex functions and special functions required to understand physical phenomena and physical processes related to Earth and Planetary Sciences.
By completing this course, students will be able to
(1) Understand the theorem of residue correctly, and carry out complex integrals using the theorem.
(2) Understand special functions, and solve physical problems related to Earth and Planetary Sciences by using them.
Mathematics for physics, Complex function, Regularity of complex function, Cauchy's integral formula, Theorem of residue, Special function, Bessel function, Legendre function
✔ Specialist skills | Intercultural skills | Communication skills | Critical thinking skills | ✔ Practical and/or problem-solving skills |
At the beginning of each class, solutions to exercise problems that were assigned during the previous class are reviewed. Towards the end of class, students are given exercise problems related to the lecture given that day to solve.
