Proper Dirac Quantization of Free Particle on D-Dimensional Sphere [PDF]
, 1997 We show that an unambiguous and correct quantization of the second-class constrained system of a free particle on a sphere in $D$ dimensions is possible only by converting the constraints to abelian gauge constraints, which are of first class in Dirac's ...

AUTOMATIC RECTIFICATION OF BUILDING FAÇADES [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2017 Focusing mainly on the case of (near-)planar building façades, a methodology for their automatic projective rectification is described and evaluated. It relies on a suitably configured, calibrated stereo pair of an object expected to contain a minimum of

Vacuum and Spacetime Signature in the Theory of Superalgebraic Spinors
Universe, 2019 A new formalism involving spinors in theories of spacetime and vacuum is presented. It is based on a superalgebraic formulation of the theory of algebraic spinors.

spo(2|2)-Equivariant Quantizations on the Supercircle S^{1|2}
Symmetry, Integrability and Geometry: Methods and Applications, 2013 We consider the space of differential operators $mathcal{D}_{lambdamu}$ acting between$lambda$- and $mu$-densities defined on $S^{1|2}$ endowed with its standard contact structure.This contact structure allows one to define a filtration on $mathcal{D}_ ...

Resolution of strong singularities and geodesic completeness in loop quantum Bianchi-II spacetimes [PDF]
, 2017 Generic resolution of singularities and geodesic completeness in the loop quantization of Bianchi-II spacetimes with arbitrary minimally coupled matter is investigated. Using the effective Hamiltonian approach, we examine two available quantizations: one

Deformation Quantization, Quantization, and the Klein-Gordon Equation [PDF]
, 2006 The aim of this proceeding is to give a basic introduction to Deformation Quantization (DQ) to physicists. We compare DQ to canonical quantization and path integral methods.

, 2012 The effect of string and quantum gravity inspired minimum-length deformed quantization on a free, massless scalar field is studied on de Sitter background at the level of second quantization. Analytic solution of a field operator is obtained to the first

From Peierls brackets to a generalized Moyal bracket for type-I gauge theories [PDF]
, 2006 In the space-of-histories approach to gauge fields and their quantization, the Maxwell, Yang--Mills and gravitational field are well known to share the property of being type-I theories, i.e.

Dynamics in Stationary, Non-Globally Hyperbolic Spacetimes [PDF]
, 2003 Classically, the dynamics in a non-globally hyperbolic spacetime is ill posed. Previously, a prescription was given for defining dynamics in static spacetimes in terms of a second order operator acting on a Hilbert space defined on static slices.
