Raychaudhuri Equation, Geometrical Flows and Geometrical Entropy

نویسندگان

چکیده

The Raychaudhuri equation is derived by assuming geometric flow in space–time M of n+1 dimensions. turns into a harmonic oscillator form under suitable transformations. Thereby, relation between geometrical entropy and mean geodesic deviation established. This has connection to chaos theory where the trajectories diverge exponentially. We discuss its application cosmology black holes. Thus, we establish general relativity.

Geometrical Entropy from theLoop Quantum

We adopt the point of view that classical (Riemannian) and quantum (given by the loop quantum gravity) descriptions of geometry are macro-and micro-descriptions in the usual statistical mechanical sense. This gives rise to the notion of geometrical entropy, which is deened as the logarithm of the number of diierent quantum states which correspond to one and the same classical geometry conngurat...

Geometrical effective action and Wilsonian flows

A gauge invariant flow equation is derived by applying a Wilsonian momentum cut-off to gauge invariant field variables. The construction makes use of the geometrical effective action for gauge theories in the Vilkovisky-DeWitt framework. The approach leads to modified Nielsen identities that pose non-trivial constraints on consistent truncations. We also evaluate the relation of the present app...

Entropy and Poincaré Recurrence from a Geometrical Viewpoint

We study Poincaré recurrence from a purely geometrical viewpoint. In [8] it was proven that the metric entropy is given by the exponential growth rate of return times to dynamical balls. Here we use combinatorial arguments to provide an alternative and more direct proof of this result and to prove that minimal return times to dynamical balls grow linearly with respect to its length. Some relati...
