Method of characteristics for first order equations, Linear partial differential equations of second order (elliptic, parabolic, hypberbolic), Initial boundary value problems, Eigenvalue problems, Distributions, Weak formulation
* analysis 1-3
* differential equations 1 (solving equations of 1st and 2nd order with constant coefficients [also inhomogeneous], variation of constants, separation of variables)
* functional analysis (in particular compactness, strong/weak convergence, L^p spaces, Hilbert spaces, dual spaces, Riesz' representation theorem, linear operators, spectrum)
