PARTIAL DIFFERENTIAL EQUATIONS
First-order partial differential equations: Method of characteristics, Cauchy problem, Hamilton-Jacobi equations (including either the Hopf-Lax formula or introduction to viscosity solutions, as per audience interest). Second order partial differential equations: The Cauchy problem and classification of second order equations, Holmgren’s uniqueness theorem; Laplace equation, Heat equation, Wave equation, Some methods of solutions, Variables separable method. Brief introduction to the weak formulation (time permitting): Motivations, Dirichlet functional. Recommended Books
