On Some Mathematical Rules from the g a geometric problem of isometric embedding a surface into the Minkowski spacetime. Then, we review the formula of surface Hamiltonian and its properties. In the explanation of the definition of the Wang–Yau energy, we focus on its physical and variational feature and relate it to some previously k

https://doi.org/10.1007/978-3-642-79589-3school.” The most important application of gravitational self-force concerns metric and curvature perturbations in black hole spacetimes due to moving particles or evolving fields. However, from a practical point of view (and for teaching purposes) we have chosen to perform the whole discussion at t

The general motivations will be presented, also recalling the role of the violation of such symmetries during the early evolution of the Universe. Antimatter systems in the form of bound neutral states will be considered, because of the possibility of studying gravitational intera

The backreaction leads to an ergosphere-like region which naturally tames the usual divergence in the calculation of the partition function

In this chapter, we construct an embedding diagram for this spacetime and study the structure of its timelike and null geodesics. In the limit case in which the asympt

The radiation field is considered as constituted by photons emitted from a rigidly rotating spherical source around the compact object. Such dynamical system admi

A severe complication is that, with the exception of a few idealised cases characterised by high degrees of symmetry, the EFEs simply cannot be obtained analytically; we need a computer to get the job done. That being said, computers (for better or worse)
