Virtual copies of semisimple Lie algebras in enveloping algebras of semidirect products and Casimir operators [PDF]
, 2008 Given a semidirect product $\frak{g}=\frak{s}\uplus\frak{r}$ of semisimple Lie algebras $\frak{s}$ and solvable algebras $\frak{r}$, we construct polynomial operators in the enveloping algebra $\mathcal{U}(\frak{g})$ of $\frak{g}$ that commute with ...

Lifshitz holography: The whole shebang [PDF]
, 2014 We provide a general algorithm for constructing the holographic dictionary for any asymptotically locally Lifshitz background, with or without hyperscaling violation, and for any values of the dynamical exponents $z$ and $\theta$, as well as the vector ...

Why the Hamilton Operator Alone Is not Enough [PDF]
Foundations of Physics, 2009 In the many worlds community seems to exist a belief that the physics of a quantum theory is completely defined by it's Hamilton operator given in an abstract Hilbert space, especially that the position basis may be derived from it as preferred using decoherence techniques. We show, by an explicit example of non-uniqueness, taken from the theory of the

On local spectral properties of extended Hamilton operators
Filomat, 2022 This paper deals with local spectral properties of Extended Hamilton operators and their adjoint operators. The relationship between the local spectral properties (strongly decomposability, hyperinvariant subspace problem, etc.) of Extended Hamilton operators and the corresponding properties of their adjoint operators is obtained.

On linear stability of crystals in the Schroedinger-Poisson model [PDF]
, 2015 We consider the Schr\"odinger--Poisson--Newton equations for crystals with a cubic lattice and one ion per cell. We linearize this dynamics at the ground state and introduce a novel class of the ion charge densities which provide the stability of the ...

TOWARD THE QUANTIZATION OF BLACK HOLES
Odessa Astronomical Publications, 2016 In order to construct a quantum model of black hole (BH), we introduce a modified description of classical space-time BH (the Schwarzschild solution). We develop the Lagrangian formalism of the vacuum gravitational field in spherically symmetric space ...

A Unified Quantization of Gravity and Other Fundamental Forces of Nature
Universe, 2022 We quantized the interaction of gravity with Yang–Mills and spinor fields; hence, offering a quantum theory incorporating all four fundamental forces of nature.

Maxwell’s Equations in Homogeneous Spaces for Admissible Electromagnetic Fields
Universe, 2022 Maxwell’s vacuum equations are integrated for admissible electromagnetic fields in homogeneous spaces. Admissible electromagnetic fields are those for which the space group generates an algebra of symmetry operators (integrals of motion) that is ...

, 2008 We provide a method of converting Lagrange and Finsler spaces and their Legendre transforms to Hamilton and Cartan spaces into almost Kaehler structures on tangent and cotangent bundles. In particular cases, the Hamilton spaces contain nonholonomic lifts
