Dimensional reduction of dual topological theories [PDF]

open access: yes, 1996
We describe the reduction from four to two dimensions of the SU(2) Donaldson-Witten theory and the dual twisted Seiberg-Witten theory, i.e. the Abelian topological field theory corresponding to the Seiberg--Witten monopole equations.Comment: LateX, 6 ...

High Temperature QCD and Dimensional Reduction [PDF]

open access: yes, 2000
In this talk I will first give a short discussion of some lattice results for QCD at finite temperature. I will then describe in some detail the technique of dimensional reduction, which in principle is a powerful technique to obtain results on the long ...

Comparison of swarm intelligence algorithms for optimized band selection of hyperspectral remote sensing image

open access: yesOpen Geosciences, 2020
Swarm intelligence algorithms have been widely used in the dimensional reduction of hyperspectral remote sensing imagery. The ant colony algorithm (ACA), the clone selection algorithm (CSA), particle swarm optimization (PSO), and the genetic algorithm ...

Self-completeness and spontaneous dimensional reduction [PDF]

open access: yes, 2013
A viable quantum theory of gravity is one of the biggest challenges facing physicists. We discuss the confluence of two highly expected features which might be instrumental in the quest of a finite and renormalizable quantum gravity -- spontaneous ...

Expansion of a quantum gas in a shell trap

open access: yesNew Journal of Physics, 2022
We report the observation of the controlled expansion of a two-dimensional (2D) quantum gas confined onto a curved shell-shaped surface. We start from the ellipsoidal geometry of a dressed quadrupole trap and introduce a novel gravity compensation ...

Fermions obstruct dimensional reduction in hot QCD [PDF]

open access: yes, 2000
We have studied, for the first time, screening masses obtained from glueball-like correlators in Quantum Chromodynamics with four light dynamical flavours of quarks in the temperature range 1.5T_c < T < 3T_c, where T_c is the temperature at which the ...

A GALERKIN APPROXIMATION METHOD INCLUDING SPACE DIMENSIONAL REDUCTION - APPLIED FOR SOLUTION OF A HEAT CONDUCTION EQUATION [PDF]

open access: yesApplied Computer Science, 2012
A multivariate data fitting procedure, based on the Galerkin minimization method, is studied in this paper. The main idea of the developed approach consists in projecting the set of data points from the original, higherdimensional space, onto a line ...

Foliation-Based Approach to Quantum Gravity and Applications to Astrophysics

open access: yesUniverse, 2019
The recently proposed holography-inspired approach to quantum gravity is reviewed and expanded. The approach is based on the foliation of the background spacetime and reduction of the offshell states to the physical states.

Search efficiency in the Adam–Delbrück reduction-of-dimensionality scenario versus direct diffusive search

open access: yesNew Journal of Physics, 2022
The time instant—the first-passage time (FPT)—when a diffusive particle (e.g., a ligand such as oxygen or a signalling protein) for the first time reaches an immobile target located on the surface of a bounded three-dimensional domain (e.g., a hemoglobin
