Dimension and Dimensional Reduction in Quantum Gravity

Universe, 2019
If gravity is asymptotically safe, operators will exhibit anomalous scaling at the ultraviolet fixed point in a way that makes the theory effectively two-dimensional.

On the Dimensional Reduction Procedure [PDF]

, 2000
The issue related to the so-called dimensional reduction procedure is revisited within the Euclidean formalism. First, it is shown that for symmetric spaces, the local exact heat-kernel density is equal to the reduced one, once the harmonic sum has been ...

Gauged supergravity from dimensional reduction [PDF]

, 1997
We perform a generalised Scherk-Schwarz reduction of the effective action of the heterotic string on T6 to obtain a massive N = 4 supergravity theory in four dimensions.

Classical aspects of lightlike dimensional reduction [PDF]

, 2006
Some aspects of lightlike dimensional reduction in flat spacetime are studied with emphasis to classical applications. Among them the Galilean transformation of shadows induced by inertial frame changes is studied in detail by proving that, (i) the ...

Compressing Fisher Vector for Robust Face Recognition

IEEE Access, 2017
One major topic for robust face recognition could be the efficient encoding of facial descriptors. Among various encoders, Fisher vector (FV) is one of the probabilistic methods that yield promising results.

Supersymmetry Breaking by Dimensional Reduction over Coset Spaces [PDF]

, 2000
We study the dimensional reduction of a ten-dimensional supersymmetric E_8 gauge theory over six-dimensional coset spaces. We find that the coset space dimensional reduction over a symmetric coset space leaves the four dimensional gauge theory without ...

Emergence of time persistence in a data-driven neural network model

eLife, 2023
Establishing accurate as well as interpretable models of network activity is an open challenge in systems neuroscience. Here, we infer an energy-based model of the anterior rhombencephalic turning region (ARTR), a circuit that controls zebrafish swimming
