CONFORMAL GEOMETRY AND ELEMENTARY PARTICLES
Proceedings of the National Academy of Sciences, 1954 The kinematical consequences of basing (classical or quantum) field theory on the conformal geometry are examined in this paper. The space in question is that of all spheres inR 4 (flat 4-space of signature (+++−)); the fundamental invariant, the angle under which two spheres intersect.

Phase space quantization and Loop Quantum Cosmology: a Wigner function for the Bohr-compactified real line [PDF]
, 2008 We give a definition for the Wigner function for quantum mechanics on the Bohr compactification of the real line and prove a number of simple consequences of this definition. We then discuss how this formalism can be applied to loop quantum cosmology. As

Observer‐Based Adaptive Event‐Triggered Tracking Control for Fuzzy TS Systems With Premise Mismatch
International Journal of Adaptive Control and Signal Processing, EarlyView.This paper presents an adaptive logistic event‐triggered observer‐based tracking controller for Takagi‐Sugeno fuzzy systems under constrained inputs and network delays. Leveraging a hybrid LMI and Secretary Bird Optimization approach, this strategy significantly minimizes communication overhead and computational burden while ensuring optimal reference ...

On the motion of bodies based on changes in the kinetic moment
RUDN Journal of Engineering Research, 2019 The controlled motion of a body in a central gravitational field without mass flow is considered. The possibility of moving the body in the radial direction from the center of attraction due to changes in the kinetic moment relative to the center of mass

A New Method for Calculating the Energies Associated with Particle Reactions
Reports in Advances of Physical SciencesA new method in which the energy and mass of elementary particles can be calculated is presented. Gluon-gluon interactions within a single elementary particle are considered, and the number of possible interactions per particle is determined.
