Ueber Eigenwerte Symmetrischer Membranen,le monotonicity arguments. In the present case of symmetric domains, it is important to know their conformal radius (mapping radius) at the center of symmetry. For some symmetric domains there is an exact elementary ratio of the conformal radii. Also, some symmetric membranes have the same first eigenvalue.

Hartree-Fock Methods a Realization of Variational Methods in Computing Energy Levels in Atoms,In this paper the well known Hartree-Fock methods are interpreted as variational methods. Since good and reliable upper bounds for the lowest eigenvalue of the Schrödinger equation are very important, we discuss the different kinds of numerical errors during the computation and give some hints how to control them.

An Elementary Proof of Monotony of the Temple Quotients,Monotony of the Temple quotients has been proved recently by F. Goerisch and J. Albrecht in their common work . In the present paper, another proof — let us call it an elementary one — of this fact is presented.
