Eddington-inspired-Born–Infeld tensorial instabilities neutralized in a quantum approach
European Physical Journal C: Particles and Fields, 2020 The recent direct detection of gravitational waves has highlighted the huge importance of the tensorial modes in any extended gravitational theory. One of the most appealing approaches to extend gravity beyond general relativity is the Eddington-inspired-

The geodesic problem in quasimetric spaces [PDF]
, 2008 In this article, we study the geodesic problem in a generalized metric space, in which the distance function satisfies a relaxed triangle inequality $d(x,y)\leq \sigma (d(x,z)+d(z,y))$ for some constant $\sigma \geq 1$, rather than the usual triangle ...

European Physical Journal C: Particles and Fields, 2020 It is well known that quantum effects may lead to removal of the intrinsic singularity point of back holes. Also, the quintessence scalar field is a candidate model for describing late-time acceleration expansion.

Probing the geometry of the Laughlin state
New Journal of Physics, 2016 It has recently been pointed out that phases of matter with intrinsic topological order, like the fractional quantum Hall states, have an extra dynamical degree of freedom that corresponds to quantum geometry.

Metric minimizing surfaces revisited
, 2018 A surface which does not admit a length nonincreasing deformation is called metric minimizing. We show that metric minimizing surfaces in CAT(0) spaces are locally CAT(0) with respect to their intrinsic ...

From Petrov-Einstein to Navier-Stokes in Spatially Curved Spacetime
, 2011 We generalize the framework in arXiv:1104.5502 to the case that an embedding may have a nonvanishing intrinsic curvature. Directly employing the Brown-York stress tensor as the fundamental variables, we study the effect of finite perturbations of the ...

Certain investigations of sequential warped product submanifolds on cosymplectic manifolds
Journal of Inequalities and Applications, 2023 In a special class of almost contact metric manifolds known as cosymplectic manifolds, the current study aims to establish the existence result and a few inequalities for sequential warped product submanifolds.

Empirical geodesic graphs and CAT(k) metrics for data analysis
, 2019 A methodology is developed for data analysis based on empirically constructed geodesic metric spaces. For a probability distribution, the length along a path between two points can be defined as the amount of probability mass accumulated along the path ...

An intrinsic construction of Fefferman’s CR metric [PDF]
Pacific Journal of Mathematics, 1986 Let M be a strictly pseudoconvex CR manifold, K be the line bundle of the \((n+1,0)\)-forms on M and let \(C=K/R^+\). Assuming K has a closed section, the author constructs intrinsically a conformal class of Lorentz metrics on the circle bundle C. In the case when the CR structure is that of a hypersurface in \({\mathbb{C}}^{n+1}\), this construction ...
