One motivation for studying Aharoni’s conjecture is that it is a strengthening of the Caccetta-Häggkvist conjecture on digraphs from 1978. In this article, we present a survey of Aharoni’s

Wolfgang Nentwig,Sven Bacher,Roland Brandlwidth. This includes examples that are far from the ‘usual suspects’. Our results imply that treewidth and Hadwiger number are linearly tied on the class of circle graphs, and that the unavoidable induced subgraphs of a vertex-minor-closed class with large treewidth are the usual suspects if and onl

Das eigenständige Dritte des MarktesWe reorganize the derivative expansion of general (power-counting nonrenormalizable) 2d dilaton gravity such that the mass function is integrable. As an example, we consider a three-parameter family of models and provide conditions on the parameters such that the ground state is either Minkowski, Rindler, or (A)dS.
