The Strong Cosmic Censorship conjecture states that for generic initial data to Einstein's field equations, the maximal globally hyperbolic development is inextendible. We prove this conjecture in the class of orthogonal Bianchi class B perfect fluids and vacuum spacetimes, by showing that unboundedness of certain curvature invariants such as the Kretschmann scalar is a generic property. The only spacetimes where this scalar remains bounded exhibit local rotational symmetry or are of plane wave equilibrium type.We further investigate the qualitative behaviour of solutions towards the initial singularity. To this end, we work in the expansion-normalised variables introduced by Hewitt-Wainwright and show that a set of full measure, which is also a countable intersection of open and dense sets in the state space, yields convergence to a specific subarc of the Kasner parabola. We further give an explicit construction enabling the translation between these variables and geometric initial data to Einstein's equations. Conjecture 1.1 (Strong Cosmic Censorship). For generic initial data to Einstein's equations, the maximal globally hyperbolic development (MGHD) is inextendible.Date: November 13, 2018. 1 2 K. RADERMACHERwhich in a first step generalise to the spatially homogeneous and isotropic Friedman-Lemaître-Robertson-Walker spacetimes. These can be further generalised to the spatially homogeneous Bianchi spacetimes which admit a three-dimensional symmetry group. Some of the Bianchi spacetimes in turn appear as special cases of G 2 cosmologies, where the symmetry group is only of dimension two. In this paper, we discuss the case of Bianchi spacetimes. The expectation is that the results obtained here will in part translate to the more general G 2 cosmologies and pave the way for the fully general setting.The terms generic and inextendible in the conjecture have to be made precise in order to obtain a meaningful statement. What we mean by genericity will become clear below. There are first results on inextendibility in the C 0 -sense (for Schwarzschild, [Sbi15], and for certain spherically symmetric spacetimes, [Chr99] and [GL16]), but here we consider inextendibility in the C 2 -sense, as we can then replace Conjecture 1.1 with the following, stronger conjecture (see [Rin09, Conj. 17.2]). Conjecture 1.2 (Curvature blow up). For generic initial data to Einstein's equations, the Kretschmann scalar R αβγδ R αβγδ is unbounded in the incomplete directions of causal geodesics in the maximal globally hyperbolic development (MGHD).
In this article, we examine corporate architecture as an effective signal to knowledge workers in the recruiting process. Two types of corporate architecture that are common in the knowledge economy are distinguished: traditional functionalist and new functionalist architecture. New functionalist architecture combines a flat, transparent facade with semi-open office layouts including areas for social interaction. Holistically these functional elements signal and symbolize a non-bureaucratic, non-hierarchical organization. A conjoint analysis provides a first attempt to quantify how much students care for new functionalist architecture. Students' stated preferences imply that they would forgo on average 10% of their starting salary in order to work in the new functionalist rather than the traditional functionalist workplace. The magnitude of this effect supports the view that architecture matters for job choice. Limitations of our study and directions for future research are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
