“…Our investigation is therefore part of the efforts aimed at a better understanding of the circumstances under which one can predict formation of shock-wave geometries [10] in classical or quantum gravity [11][12][13][14]. In future work, we hope to be able to study the "boosted" Riemann tensor, along the lines of [3], but for Schwarzschild-de Sitter, Schwarzschild-anti-de Sitter (see previous sections) and Kerr-Schild geometries [4].…”

The problem of deriving a shock-wave geometry with cosmological constant by boosting a Schwarzschild-de Sitter (or anti-de Sitter) black hole is re-examined. Unlike previous works in the literature, we deal with the exact Schwarzschild-de Sitter (or anti-de Sitter) metric. In this exact calculation, where the metric does not depend linearly on the mass parameter, we find a singularity of distributional nature on a null hypersurface, which corresponds to a shock-wave geometry derived in a fully non-perturbative way. The result agrees with previous calculations, where the metric had been linearized in the mass parameter.

“…It should be analyzed to what extent W a and P a yield information about the helicity of plane gravitational waves, for instance. We recall that investigations about the possible existence of spin-1 gravitational waves have been carried out in the literature [25]. This issue will considered in the context of the present analysis.…”

“…The other components also vanish, M (1)(3) = M (2)(3) = 0, and consequently the angular momentum L (i)(j ) of the spacetime of a rotating mass shell vanishes if computed out of equation (25). However this result should come as no surprise, since the reference frame represented by equation ( 25) is rotating around the source with angular velocity .…”

We redefine the gravitational angular momentum in the framework of the teleparallel equivalent of general relativity. In similarity to the gravitational energy-momentum, the new definition for the gravitational angular momentum is coordinate independent. By considering the Poisson brackets in the phase space of the theory, we find that the gravitational energy-momentum and angular momentum correspond to a representation of the Poincaré group. This result allows us to define Casimir type invariants for the gravitational field.

Goods, Persons, Services and Capital in the European Union: Jurisprudential Routes to Free Movement

This Paper considers the jurisprudence of the Court of Justice in relation to the free movement provisions of European Community law in relation to goods, persons, services and capital within the European Union. It examines the bases used by the Court in its application of Community free movement provisions to national measures that may seek to hinder the exercise of such rights. From limited enquiry originally founded on considerations of non discrimination based on nationality, to one most recently focussed on the ‘restriction’ to the free movement right, the Paper examines the methods employed by the Court of Justice in its scrutiny of the national measure appearing to conflict with Treaty free movement rights.The examination of the applicable free movement jurisprudence attempts to demonstrate the want of a thematically consistent underpinning within free movement case law. The Paper draws attention to the complexities and even the confusions that appear to be inherent within free movement jurisprudence and arguably evidenced within the Court's journey from ‘discrimination’ to ‘restriction’ as the basis of the enquiry with regard to the application of Treaty free movement rights. In its consideration of Case C-110/05 Commission v Italy, Case C-142/05 Åklagaren v. Percy Mickelsson v. Joakim Roos, recent jurisprudence with respect to the free movement of goods, the Paper notes that in the context of the ‘measure having equivalent effect’, the emphasis in the assessment of the national rule has shifted to an examination of the effect on market access, rather than a distinction based on the type of rule.
