Nonlocal action for long - distance modifications of gravity theory
We construct the covariant nonlocal action for recently suggested long-distance modifications of gravity theory motivated by the cosmological constant and cos-mological acceleration problems. This construction is based on the special non-local form of the Einstein-Hilbert action explicitly revealing the fact that this action within the covariant curvature expansion begins with curvature-squared...
متن کاملNew Nonlocal Effective Action
We suggest a new method for the calculation of the nonlocal part of the effective action. It is based on the resummation of the perturbation series for the heat kernel and its functional trace at large values of the proper time parameter. We derive a new, essentially nonperturbative, nonlocal contribution to the effective action in spacetimes with dimensions d > 2.
متن کاملSpace-Adiabatic Perturbation Theory
We study approximate solutions to the Schrödinger equation iε∂ψt(x)/∂t = H(x,−iε∇x)ψt(x) with the Hamiltonian H the Weyl quantization of the symbol H(q, p) taking values in the space of bounded operators on the Hilbert space Hf of fast “internal” degrees of freedom. By assumption H(q, p) has an isolated energy band. We prove that interband transitions are suppressed to any order in ε. As a cons...
متن کاملModalities over Action, I. Model Theory
This paper analyzes a language for actions and the deontic modalities over actions — i.e., the modalities permitted, forbidden and obligatory. The work is based on: (1) an action language that allows the representation of concurrent and repetitive events; (2) a deontic language that allows the representation of “free choice permissions”; (3) a proof procedure that admits a logic programming sty...
