Course Content

Introduction to partial differential equations ? The first order equations: a linear equation, a quasilinear equation, resolving the initial value problem by the method of characteristic curves. ? Classification of the second order equations: elliptic, hyperbolic and parabolic equations, exam- ples of Laplace, Wave and Heat equations. ? Elliptic equations: Laplace and Poisson?s equations, Dirichlet and Neumann boundary value problems, Poisson?s kernel, Green?s functions, properties of harmonic functions, Maximum prin- ciple. ? Analytical methods for resolving partial differential equations: Sturm-Liouville problem and the method of separation of variables for bounded domains, applications for Laplace, Wave and Heat equations including non-homogenous problems. Applications of Fourier and Laplace transforms for resolving problems in unbounded domains. ? Heat equation: initial value problem in unbounded domain, basic formula for the solution, initial-boundary value problems in bounded domains, Maximum principle. ? Wave equation: Dalamber formula, non-homogenous equation, Wave equation in higher dimen- sions. ? If time permits: Legendre polynomials and spherical functions. Literature: ?
