Events and observables in generally invariant spacetime theories
We address the problem of observables in generally invariant spacetime theories such as Einstein’s general relativity. Using the refined notion of an event as a “point-coincidence” between scalar fields that completely characterise a spacetime model, we propose a generalisation of the relational local observables that does not require the existence of four everywhere invertible scalar fields. T...
متن کاملThermodynamics of spacetime in generally covariant theories of gravitation
It has been shown that the Einstein equation can be derived from the requirement that the First Law δQ = TdS holds for all local Rindler causal horizons through each spacetime point. Here δQ and T are the energy flux and Unruh temperature seen by an accelerating observer just inside the horizon, and the entropy S is one quarter the horizon area in Planck units. In this paper we show that there ...
متن کاملPrecision observables and electroweak theories
We compute the bounds from precision observables on alternative theories of electroweak symmetry breaking. We show that a cutoff as large as 3 TeV can be accommodated by the present data, without any new particles or unnatural fine tuning.
متن کاملIssue of time in generally covariant theories and the Komar-Bergmann approach to observables in general relativity
1550-7998=20 Diffeomorphism-induced symmetry transformations and time evolution are distinct operations in generally covariant theories formulated in phase space. Time is not frozen. Diffeomorphism invariants are consequently not necessarily constants of the motion. Time-dependent invariants arise through the choice of an intrinsic time, or equivalently through the imposition of time-dependent ...
متن کاملSteerable filters and invariant recognition in spacetime
The groups which have received most attention in signal processing research are the affine groups and the HeisenbergWeyl group related to wavelets and time-frequency methods. In low-level image processing the rotation-groups SO(2) and SO(3) were studied in detail. In this paper we argue that the Lorentz group SO(1; 2) provides a natural framework in the study of dynamic processes like the analy...
