Darstellungen der Algebren durch Matrizes,on of the spectrum, and we give various criteria (via Weyl sequences) to characterize these spectra. We also prove the famous min-max theorem, which characterizes the low lying eigenvalues of a self-adjoint operator bounded from below. This chapter is illustrated by means of various canonical examples, such as the Hamiltonian of the hydrogen atom.
