Dimensional reduction of the generalized DBI
We study the generalized Dirac–Born–Infeld (DBI) action, which describes a q-brane ending on a p-brane with a (q+1)-form background. This action has the equivalent descriptions in commutative and non-commutative settings, which can be shown from the ...

Dimensional reduction on a sphere [PDF]
The question of the dimensional reduction of two-dimensional (2d) quantum models on a sphere to one-dimensional (1d) models on a circle is adressed. A possible application is to look at a relation between the 2d anyon model and the 1d Calogero-Sutherland

On the Dimensional Reduction Procedure [PDF]
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 ...

Spontaneous Dimensional Reduction? [PDF]
Over the past few years, evidence has begun to accumulate suggesting that spacetime may undergo a "spontaneous dimensional reduction" to two dimensions near the Planck scale.

Dimensional reduction in the sky [PDF]
We explore the cosmological implications of a mechanism found in several approaches to quantum-gravity, whereby the spectral dimension of spacetime runs from the standard value of 4 in the infrared (IR) to a smaller value in the ultraviolet (UV ...

From Topology to Generalised Dimensional Reduction [PDF]
In the usual procedure for toroidal Kaluza-Klein reduction, all the higher-dimensional fields are taken to be independent of the coordinates on the internal space.

Dimensional Reduction for Conformal Blocks [PDF]
We consider the dimensional reduction of a CFT, breaking multiplets of the d-dimensional conformal group SO(d+1,1) up into multiplets of SO(d,1). This leads to an expansion of d-dimensional conformal blocks in terms of blocks in d-1 dimensions.

Dimensional Reduction by Conformal Bootstrap [PDF]
The dimensional reductions in the branched polymer and the random field Ising model (RFIM) are discussed by a conformal bootstrap method. The small size minors are applied for the evaluations of the scale dimensions of these two models and the results ...

Torsion in cohomology and dimensional reduction
Conventional wisdom dictates that ℤ N factors in the integral cohomology group H p (X n , ℤ) of a compact manifold X n cannot be computed via smooth p-forms.

The dynamics of coset dimensional reduction [PDF]
The evolution of multiple scalar fields in cosmology has been much studied, particularly when the potential is formed from a series of exponentials. For a certain subclass of such systems it is possible to get `assisted` behaviour, where the presence of ...
