授業の概要・目的 We study solutions of partial and ordinary differential equations, such as trigonometric functions, Bessel functions, Legendre functions. As applications of these eigen functions, we study Fourier series, Fourier and Laplace transforms, which are mathematical bases of electrical engineering and electronics, plasma physics, and quantum mechanics.
到達目標 Understanding mathematical methods for discription of physical phenomena evolving in space and time.
授業計画と内容 1st and 2nd lectures:
Classification of partial differential euqaions(PDE).
Derivation of ordinary differential equations (ODE) frmo typical PDE in Catesian coordinates, polar cyclindrical coordinates, and circular spherical coordinates.

3rd and 4th lectures:
Series solutions by Frobenius' method; trigonometric, Bessel, and Legendre functions. Singular points for ODE; Wronskian; linear indepedence of solutions; second solution
Sturn-Liouville Theory

5th and 6th lectures: Self-ajoint ODE; Hermitian operator; Sturm-Liouville theory Green's Function Method, Green's function method to solve nonhomogeneous equation, Bessel Functions

7th and 8th lectures:

9th and 10th lectures:
Legendre functions; generating functions; boundary value problems; associated Legendre polynomials, Fourier Series

11th and 12th lectures:

成績評価の方法・観点 The grade is determined by adding the scores of report assignments (5 points x 12 times) and a term test (100 points). If the total socre exceeds 100 points, the score is given as 100.
履修要件 Calculus, Vector Analysis, Complex Variables, and English listening comprehention at the level of VOS special english.

授業外学習(予習・復習)等 Reprot assignments are announced at every lecture, and the report should be submitted at the beginning of the next lecture.
