The Entropy of Black Holes via Noether’s Theorem of black holes starting from suitable variations of superpotentials. Superpotentials are associated to Noether currents and are properly defined in any gauge-natural field theory. In this covariant framework the entropy is defined in such a way that it automatically satisfies the first principle of

Dual Lagrangian Theoriesween certain relativistic theories of gravitation and general relativity. The theory of dual Lagrangians for gauge theories is studied in detail. As an example, we describe SO(3) and SO(2,1) Yang-Mills theories on 3-dimensional and 4-dimensional manifolds.

The Search for Gravitational Waves with Resonant Detectorsbeen in operation and data have been recorded by EXPLORER, ALLEGRO, NIOBE, NAUTILUS and AURIGA. The sensitivity for pulse detection with SNR=1 is now . ∼ 4 · 10. (corresponding to a total energy of less than 0.001 solar masses for a source in the Galactic Center). The sensitivity for monochromatic w

Cauchy-Perturbative Matching and Outer Boundary Conditionss. Our approach matches the solution of a Cauchy evolution of Einstein’s equations to a set of one-dimensional linear wave equations on a curved background. We illustrate the mathematical properties of our approach and discuss a numerical module we have constructed for this purpose. This module impl

Conference proceedings 2000 1998. The Conference, which is held every other year in different Italian locations, has brought together, as in the earlier conferences in this series, those scientists who are interested and actively work in all aspects of general relativity, from both the mathematical and the physical points of

Special Relativity at Action in the Universefferent parts of the source, they travel different paths to reach the observer, depending on the viewing angle. The object is seen rotated, not contracted, and at small viewing angles time intervals are observed shorter than intrinsic ones.
