On the Dirac eigenvalues as observables of the on-shell N = 2D = 4 Euclidean supergravity

We generalize previous works on the Dirac eigenvalues as dynamical variables of Euclidean gravity and N =1 D = 4 supergravity to on-shell N = 2 D = 4 Euclidean supergravity. The covariant phase space

Nonlinear connections and spinor geometry

TLDR
Strong arguments for application of Finsler-like geometries in modern string and gravity theory, noncommutative geometry and noncommUTative field theory, and gravity are emphasized.

Exact solutions with noncommutative symmetries in Einstein and gauge gravity

We present new classes of exact solutions with noncommutative symmetries constructed in vacuum Einstein gravity (in general, with nonzero cosmological constant), five-dimensional (5D) gravity and

Nonholonomic Clifford Structures and Noncommutative Riemann-Finsler Geometry

We survey the geometry of Lagrange and Finsler spaces and discuss the issues related to the definition of curvature of nonholonomic man- ifolds enabled with nonlinear connection structure. It is

CONSTRAINTS ON SPACE–TIME MANIFOLD IN EUCLIDEAN SUPERGRAVITY IN TERMS OF DIRAC EIGENVALUES

We generalize a previous work on Dirac eigenvalues as dynamical variables of Euclidean supergravity. The most general set of constraints on the curvatures of the tangent bundle and on the spinor

Observables of Euclidean Supergravity

The set of constraints under which the eigenvalues of the Dirac operator can play the role of the dynamical variables for Euclidean supergravity is derived. These constraints arise when the gauge

On Local Constraints of D=4 Supergravity in Terms of Dirac Eigenvalues

It has been recently shown that in order to have Dirac eigenvalues as observables of Euclidean supergravity, certain constraints should be imposed on the covariant phase space as well as on Dirac

General Relativity in Terms of Dirac Eigenvalues

The eigenvalues of the Dirac operator are diffeomorphism-invariant functions of the geometry, namely, ``observables'' for general relativity. Recent work by Chamseddine and Connes suggests taking

Euclidean supergravity in terms of Dirac eigenvalues

It has been recently shown that the eigenvalues of the Dirac operator can be considered as dynamical variables of Euclidean gravity. The purpose of this paper is to explore the possiblity that the

Gravity from Dirac Eigenvalues

We study a formulation of Euclidean general relativity in which the dynamical variables are given by a sequence of real numbers λn, representing the eigenvalues of the Dirac operator on the curved

Observables in quantum gravity

We study a family of physical observable quantities in quantum gravity. We denote them W functions, or n-net functions. They represent transition amplitudes between quantum states of the geometry,

GPS observables in general relativity

I present a complete set of gauge invariant observables, in the context of general relativity coupled with a minimal amount of realistic matter (four particles). These observables have a

Partial observables

I discuss the distinction between the notion of partial observable and the notion of complete observable. Mixing up the two is frequently a source of confusion. The distinction bears on several
