WebJun 19, 2024 · Taking a spacetime average as a measure of the strength of singularities we show that big-rips (type I) are stronger than big-bangs. The former have infinite spacetime averages while the latter have them equal to zero. The sudden future singularities (type II) and w−singularities (type V) have finite spacetime averages.

A singularity in solutions of the Einstein field equations is one of two things: 1. a situation where matter is forced to be compressed to a point (a space-like singularity) 2. a situation where certain light rays come from a region with infinite curvature (a time-like singularity) Web5.1.4 Long wavelength limit. We observe that away from the van Hove singularities, the absorption enhancement factor in a photonic crystal is in general lower than the 2 πn limit. This is partly due to the fact that the overlap factor Γ is lower than the area or volume fraction, and, more importantly, due to the lower effective DOS of the ... sap dbtech jdbc 258 insufficient privilege
