Riemannian Maps

open access: yes, 2017
In this chapter, we study Riemannian maps between Riemannian manifolds. In section 1, we define Riemannian maps and give the main properties of such maps. In section 2, we obtain Gauss-Weingarten-like formulas and then we obtain Gauss, Codazzi, and Ricci

CFT complexity and penalty factors

open access: yesJournal of High Energy Physics
Quantum complexity of conformal field theory (CFT) states has recently gained significant attention, both as a diagnostic tool in condensed matter systems and in connection with holographic observables probing black hole interiors.

Chiral interactions of fermions and massive gauge fields in Kaluza-Klein models

open access: yesJournal of High Energy Physics
In Kaluza-Klein theory, gauge fields on M 4 arise as components of a higher-dimensional metric defined on M 4 × K. The traditional expectation is that all the gauge fields of the Standard Model are linked to exact Killing vector fields on the internal ...

Canonical submersions in nearly Kähler geometry

open access: yesComplex Manifolds
We explore submersions introduced by reducible holonomy representations of connections with parallel skew torsion. A submersion theorem extending previous, less general, results is given. As our main application, we show that parallel 3-(α,δ)\left(\alpha

Slant submersions from almost product Riemannian manifolds

open access: yes, 2013
In this paper, we define the concept of almost product Riemannian submersion between almost product Riemannian manifolds. We introduce slant submersions from almost product Riemannian manifolds onto Riemannian manifolds.

Internal symmetries in Kaluza-Klein models

open access: yesJournal of High Energy Physics
The usual approach to Kaluza-Klein considers a spacetime of the form M 4 × K and identifies the isometry group of g K 0 $$ {g}_K^0 $$ , the internal vacuum metric, with the gauge group in four dimensions.

Semi-Riemannian submersions with totally geodesic fibres

open access: yes, 2004
We classify semi-Riemannian submersions with connected totally geodesic fibres from a real pseudo-hyperbolic space onto a semi-Riemannian manifold under the assumption that the dimension of the fibres is less than or equal to three.

A finiteness theorem for Riemannian submersions [PDF]

open access: yes, 1992
Given some geometric bounds for the base space and the fibres, there is a finite number of conjugacy classes of Riemannian submersions between compact Riemannian ...

Para-contact product semi-Riemannian submersions

open access: yes, 2017
We introduce the concept of para-contact product semi-Riemannian submersions from an almost para-contact metric manifold onto a semi-Riemannian product manifold.
