dc.description.abstract	In contrast to classical physics, there are not too many mathematical tools facilitating the study of singularities in quantum systems. One of the exceptions is Kato's notion of exceptional points (EPs). Their emergence and localization are analyzed here via a family of schematic toy models.	eng
