The making of Calabi-Yau spaces: Beyond toric hypersurfaces

While Calabi-Yau hypersurfaces in toric ambient spaces provide a huge number of examples, theoretical considerations as well as applications to string phenomenology often suggest a broader perspective. With even the question of finiteness of diffeomorphism types of CY 3-folds unsettled, an important idea is Reid's conjecture that the moduli spaces are connected by certain singular transitions. We summarize the results of our recent construction of a large class of new CY spaces with small Picard numbers and of their mirrors via conifold transitions and discuss the benefits of other approaches to interesting locations in the web that have been or should be pursued.Comment: 6 page

Symmetries of Analytic Curves

Analytic curves are classified w.r.t. their symmetries under a regular Lie group action on an analytic manifold. We show that an analytic curve is either exponential or splits into countably many analytic immersive curves; each of them decomposing naturally into symmetry free subcurves mutually and uniquely related by the group action. We conclude that a connected analytic 1-dimensional submanifold is either analytically diffeomorphic to the unit circle or some interval, or that each point (except for at most countably many) admits a symmetry free chart.Comment: 49 page

International Migration as Absolute Natural Law: An Inquiry into International Migration from the Perspective of Legal Philosophy

This paper investigates to what extent international migration law is coherent with the concept of migration as a natural human right. Based on the assumption that migration is an inherently human behavior, beneficial to humankind, and therefore natural law, an analysis of the most prominent sources of international migration law is undertaken. The result of the analysis shows that modern international migration law is largely in line with the concept of natural law, and that the criminalization of migration happens on the domestic level, where economic and populist motivations inform policy makers and shape the law
