Uniqueness Theorems for Black Hole Space-Times
This lecture gives a brief outline of the proof of the black hole uniqueness theorem. Since the latter applies to stationary space-times, we first...

Metric reconstruction from celestial multipoles
The most general vacuum solution to Einstein’s field equations with no incoming radiation can be constructed perturbatively from two infinite sets of...

On parity-odd sector in metric-affine theories
We undertake the construction of quadratic parity-violating terms involving the curvature in the four-dimensional metric-affine gravity. We...

Influence of Space Curvature on the Moment of Inertia of a Pulsar Magnetic Field
AbstractWe consider the influence of space curvature in the Schwarzschild metric on the contribution of the magnetic field outside the neutron star...

Bulk reconstruction of AdSd+1 metrics and develo** kinematic space
The metrics of the global, Poincaré, and Rindler AdS d +1 are explicitly reconstructed with given lightcone cuts. We first compute the metric up to a...

A note on uncertainty relations of metric-adjusted skew information
The uncertainty principle is one of the fundamental features of quantum mechanics and plays a vital role in quantum information processing. We study...

Coordinate-Independent Definition of Relative Velocity in Pseudo-Riemannian Space-Time: Implications for Special Cases
AbstractUsing the general solution that we recently obtained for the coordinate-independent definition of a relative velocity of a luminous source as...

Arbitrary Static, Spherically Symmetric Space-Times as Solutions of Scalar-Tensor Gravity
AbstractIt is shown that an arbitrary static, spherically symmetric metric can be presented as an exact solution of a scalar-tensor theory (STT) of...

An embedding space approach to Carrollian CFT correlators for flat space holography
Carrollian conformal field theories (carrollian CFTs) are natural field theories on null infinity of an asymptotically flat spacetime or, more...

Metric-affine cosmological models and the inverse problem of the calculus of variations. Part 1: variational bootstrap** – the method
The method of variational completion allows one to transform an (in principle, arbitrary) system of partial differential equations – based on an...

Pregeometry and spontaneous time-space asymmetry
In pregeometry a metric arises as a composite object at large distances. We investigate if its signature, which distinguishes between time and space,...

Galilean Metric Field
The fibring of spacetime over time naturally yields a natural scaled timelike metric with signature...

The Extended Einstein–Maxwell-Aether-Axion Theory: Effective Metric as an Instrument of the Aetheric Control over the Axion Dynamics
AbstractIn the framework of the Einstein–Maxwell-aether-axion theory, we consider a self-consistent model based on the concept of two-level control,...

The nature of cosmological metric perturbations in presence of gravitational particle production
The present paper tries to answer the question: Can a de Sitter phase in presence of radiation be a competitor of the standard inflationary paradigm...

Geometric Proca with matter in metric-Palatini gravity
In the present work, we study linear, torsion-free metric-Palatini gravity, extended by the quadratics of the antisymmetric part of the Ricci tensor...

Dimensionless Physics: Planck Constant as an Element of the Minkowski Metric
Diakonov theory of quantum gravity, in which tetrads emerge as the bilinear combinations of the fermionic fields, suggests that in general relativity...

Periodic-chaotic alternating regimes during a fast solar metric-radio pulsation event
In the magnetically dominated corona, loop-like structures are expected to undergo pulsating events which are highly structured in time and...

Flux Quantization on Phase Space
While it has become widely appreciated that (higher) gauge theories need, besides their variational phase space data, to be equipped with “flux...

The summation and product forms of the uncertainty relations based on metric-adjusted skew information
Uncertainty principle is one of the most fundamental features in quantum mechanics and plays a significant role in quantum information processing. We...
