This first of two volumes of proceedings contains 19 technical papers on such topics as instabilities in kinetic theory and their relationship to the ergodic theorem, the uniqueness of photon spheres in static vacuum asymptotically flat spacetimes, an initial-boundary value problem in a strip for two-dimensional equations of Zacharov-Kunzhetsov type, an extension of harmonicity and holomorphy, and over-determined transforms in integral geometry.
Moreover, an EH always exists in black hole asymptotically flat space-time under a weak cosmic censorship condition and is represented by a Killing horizon such that the space-time is analytic and the stress tensor obeys the weak energy condition.

B) We know that an event horizon always exists in black hole asymptotically flat space-time and isolated horizons approximate event horizons of a black hole at late stages of gravitational collapse and can be easily located, as stated in our previous papers.
This has led many researchers to conclude that the universe is home to a multitude of black holes conforming to one of the stationary, asymptotically flat, black hole metrics --in accordance with the claim of a leading relativist that the "black holes of nature are the most perfect macroscopic objects that are in the universe" [3].
The Schwarzschild metric is asymptotically flat and, for regions far outside the event horizon, r [much greater than] [r.
The first work solves the Cauchy problem for the Einstein vacuum equations with more general, asymptotically flat initial data and then describes the asymptotic behavior.
And using the Kerr-Schild formalism, one can obtain exact asymptotically flat multiparticle solutions of the Einstein-Maxwell field equations.
