The smallest split Cayley hexagon has two symplectic embeddings

AbstractIt is well known that the smallest split Cayley generalized hexagon H(2) can be embedded into the symplectic space W(5,2), or equivalently, into the parabolic quadric Q(6,2). We establish a second way to embed H(2) into the same space and describe a computer proof of the fact that these are essentially the only two embeddings of this type

Shared scepticism, different motives: Franco-German perceptions of a common European safe asset. Bertelsmann Stiftung 26 October 2018

A common European safe asset is a highly contentious proposal within the Euro area reform agenda. Various safe asset proposals have been put forward since the onset of the Euro crisis ranging from Eurobonds to European Safe Bonds (ESBies), also known as Sovereign Bond- Backed Securities (SBBS), which currently enjoy the institutional support of the European Commission as well as the High-Level Task Force on Safe Assets at the European Systemic Risk Board. Its proponents argue that a European safe asset is required to break the bank-sovereign nexus and limit destabilising capital flows, ultimately improving financial stability in the Euro area. Nevertheless, the concept of a European safe asset remains controversial among national policymakers; some consider the idea promising, while others see it as a threat to market discipline, national sovereignty, or long-term fiscal stability

Hidden Hot Dark Matter as Cold Dark Matter

We show that hidden hot dark matter, hidden-sector dark matter with interactions that decouple when it is relativistic, is a viable dark matter candidate provided it has never been in thermal equilibrium with the particles of the standard model. This hidden hot dark matter may reheat to a lower temperature and number density than the visible Universe and thus account, simply with its thermal abundance, for all the dark matter in the Universe while evading the typical constraints on hot dark matter arising from structure formation. We find masses ranging from ~3 keV to ~10 TeV. While never in equilibrium with the standard model, this class of models may have unique observational signatures in the matter power spectrum or via extra-weak interactions with standard model particles.Comment: 5 pages, 1 figur

Protecting Fundamental Labor Rights: Lessons from Canada for the United States

This paper examines the decline in unionization in the United States that began to occur in about 1960. While various explanations have been put forward to explain this -- with many focusing on some form of structural changes to the economy or to the workforce, usually related to globalization or technological progress -- this paper focuses on the role that employer opposition to unions has played, together with relatively weak labor law. In order to fully flesh out the experience of the United States, it looks to the experience of Canada as the country most similar to it
