On the geometry spaces of hyperlane elemente with special metric
Lietuvos Matematikos Rinkinys, 2008 In this paper analysies metric space of hyperlane elemente with special metric. Is prowed, that the space Kartan–Landsbeg space is. Criteria of integrability of the intrinsic almost complex and almost product structures is found.

A Pseudopolynomial Algorithm for Alexandrov's Theorem [PDF]
, 2008 Alexandrov's Theorem states that every metric with the global topology and local geometry required of a convex polyhedron is in fact the intrinsic metric of a unique convex polyhedron.

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 ...

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-

An Intrinsic Behavioral Approach to the Gap Metric [PDF]
SIAM Journal on Control and Optimization, 2006 An intrinsic trajectory level approach without any recourse to an algebraic structure of a representation is utilized to develop a behavioural approach to robust stability. In particular it is shown how the controllable behaviour can be constructed at the trajectory level via Zorn's Lemma, and this is utilized to study the controllable-autonomous ...

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 ...

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 ...

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.

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 ...

Breaking the color-reddening degeneracy in type Ia supernovae
, 2016 A new method to study the intrinsic color and luminosity of type Ia supernovae (SNe Ia) is presented. A metric space built using principal component analysis (PCA) on spectral series SNe Ia between -12.5 and +17.5 days from B maximum is used as a set of ...
