misti est une nouvelle de guy de maupassant. sur le mode de la narration à la première personne, cette nouvelle rapporte le souvenir d’un jeune homme qui fait part d’une histoire étrange qu’il a vécue dans une relation amoureuse. les deux éléments constitutifs de départ sont les questions d’amour et de superstition. des éléments textuels comme la description et la mise en abyme d’une part et, d...

The cosmological evolution of a quintessence-like scalar field φ coupled to matter and gauge fields leads to effective modifications of the coupling constants and particle masses over time. We analyze a class of models where the scalar field potential V (φ) and the couplings to matter B(φ) admit common extremum in φ, as in the Damour-Polyakov ansatz. We find that even for the simplest choices o...

We extend the classical Damour-Ruffini method and discuss Hawking radiation in KerrNewman-de Sitter(KNdS) black hole. Under the condition that the total energy, angular momentum and charge of spacetime are conserved, taking the reaction of the radiation of the particle to the spacetime and the relation between the black hole event horizon and the cosmological horizon into consideration, we deri...

This paper applies a fully post-Newtonian theory (Damour et al. 1991, 1992, 1993, 1994) to the problem of gauge in relativistic reference systems. Gauge fixing is necessary when the precision of time measurement and application reaches 10−16 or better. We give a general procedure for fixing the gauges of gravitational potentials in both the global and local coordinate systems, and for determini...

Abstract. We give a surface integral derivation of the leading-order evolution equations for the spin and energy of a relativistic body interacting with other bodies in the post-Newtonian expansion scheme. The bodies can be arbitrarily shaped and can be strongly self-gravitating. The effects of all mass and current multipoles are taken into account. As part of the computation one of the 2PN pot...
