RUSSIAN TALKS 1) I. Khriplovich "Radiation and horizon spectrum of quantized black holes". 45 min. Abstract: The maximum entropy of a quantized surface is demonstrated to be proportional to the surface area in the classical limit. The general structure of the horizon spectrum and the value of the Barbero-Immirzi parameter are found. The discrete spectrum of thermal radiation of a black hole fits naturally the Wien profile. The natural widths of the lines are very small as compared to the distances between them. The total intensity of the thermal radiation is calculated. 2) D. Galtsov "New approach to gravitational radiation reaction" (In collaboration with Pavel Spirin and Simona Staub). 45 min. Abstract: New approach to derivation of equations of motion of pointlike particles interacting with scalar, electromagnetic and gravitational fields is suggested introducing the local regularization of the self forces. It is free from ambiguities present in earlier calculations based on the integration of stress-tensor along the world-tube. In particular, we reveal the meaning of the renormalization in the gravitational case and correct some earlier results concerning scalar and gravitational radiation reaction. 3) V. Rudenko "Searches for astro-gravity correlation" 25 min. Abstract: Strategy of milti-channel search for rare gravitational pulses from relativistic sourses in Galactic and close environment is considered. Quasi-optimal algorithms of such data processing are proposed. Its relative efficiency is demonstrated with the cryojenic bar-detector noise background and BATSE GRB catalog. 4) G.A.Alekseev "Interaction of black holes with the external gravitational and electromagnetic fields" Abstract: We present a construction of a large variety of exact stationary axisymmetric solutions of Einstein - Maxwell equations which describe the examples of interaction of black holes with a wide range of the external gravitational and electromagnetic field configurations. The examples of the Schwarzschild and Nordstr\"om-Reissner black holes immersed into a homogeneous external electric and magnetic fields are presented and some relevant aspects of a black hole mechanics ...
ITALIAN TALKS
ITALIAN TALKS 1) G. Vereshchagin "Singularity-free cosmology within semi-classical loop quantum gravity" Abstract: Recent progress in loop quantum cosmology has shown that the classical singularity disappears in some important cases even within semi-classical formulation of the theory. I will discuss cosmic singularity in cosmological models with scalar field as well as models with matter hamiltonians which mimic those of perfect fluids with linear equation of state. 2) S. Mercuri and G. Montani (speaker S. Mercuri) "The contorsion field as a candidate for a gauge theory of the Lorentz group". Abstract: The role played by the contorsion field in a gauge theory of the Lorentz group is investigated. The dynamical scheme resulting from including spinor fields in the geometrodynamics is discussed in the second and first order formulation of the theory. 3) V. Belinski "On exact solutions of Einstein-Maxwell equations" Abstract: I will discuss some problems associated with physical interpretation of the exact stationary solutions of Einstein-Maxwell equations. 4) others italian talk will be announce later
