Singular Perturbations of Semi-Group Generatorsth illustrative, and of prime importance in the theory of quantum fields, which is the source of many novel problems involving singular perturbations; and it has been developed much more than the general case.

Eine Bemerkung zum Banachschen Fixpunktsatzwächen, daß der zugrunde liegende Raum . als Banachunterraum eines Banachraumes . angesehen wird und in . eine Kontraktionsbedingung, jedoch in . nur eine Beschränktheitsbedingung gefordert wird. Dieser spezielle Fixpunktsatz läßt sich auf das angegebene Problem anwenden.

Singular Perturbations of Semi-Group Generatorsterms of self-adjoint operators in Hilbert space, although the central ideas are applicable to fairly general semi-groups. The self-adjoint case is both illustrative, and of prime importance in the theory of quantum fields, which is the source of many novel problems involving singular perturbations;
