identification of singularities, asymptotic behavior,
integral and series representations, as well as
complex contour integration using basic theorems and lemmas.
Ability in computing and using the Fourier transforms.
Knowledge of the linear operator algebra in Hilbert spaces,
giving special attention to Hermitian and unitary operators.
Mastery in classifying integral and differential equations,
in proving the existence and uniqueness of the solution and
in using procedures to compute such solutions. - Prerequisites
