19 results for Autoparallelity

The paper explores quantum statistical manifolds and their autoparallelity, providing estimation-theoretical characterizations.

problem Quantum statistical manifolds and their geometric properties.
method Study of autoparallelity w.r.t. the e-connection, using quantum estimation theory.
result Characterizations of e-autoparallel submanifolds as statistical models with efficient estimators.

In this work a proposal for definition of twistors on generic curved spaces is exposed and investigated. We consider superpositions of nearly autoparallel and nearly geodesic maps (nearly conformal maps, nc-maps) of (pseudo-)Riemannian spaces as generalizations of conformal transforms. We introduce the nearly autoparal…

On the probability simplex, we can consider the standard information geometric structure with the e- and m-affine connections mutually dual with respect to the Fisher metric. The geometry naturally defines submanifolds simultaneously autoparallel for the both affine connections, which we call {\em doubly autoparallel s…

Researchers find conditions for autoparallels to be Finsler geodesics.

problem Existence of a Finsler Lagrangian metrizing autoparallels in metric-affine geometry.
method Determined necessary and sufficient conditions for Finsler metrizability of torsion-free affine connections.
result A broad class of connections is Finsler metrizable, making their autoparallels Finsler geodesics.

The statistical analysis of data lying on a differentiable, locally Euclidean, manifold introduces a variety of challenges because the analogous measures to standard Euclidean statistics are local, that is only defined within a neighbourhood of each datapoint. This is because the curvature of the space means that the c…

Absolute parallelism geometry is frequently used for physical applications. It has two main defects, from the point of view of applications. The first is the identical vanishing of its curvature tensor. The second is that its autoparallel paths do not represent physical trajectories. The present work shows how these de…

Develops a Kaluza-Klein theory in affine spaces without metric.

problem Formalizes a geometric theory of electromagnetic fields in affine spaces.
method Formulates dimensional reduction using principal fiber bundles and Ehresmann connections.
result Shows that non-integrability of horizontal distribution implies nontrivial electromagnetic fields.

The paper defines ηη-normality for contact and paracontact manifolds and explores their properties.

problem Defining and characterizing ηη-normality for contact and paracontact manifolds.
method Using the Levi-Civita covariant derivative and Tanaka-like connections.
result Existence and uniqueness of connections on ηη-normal manifolds.

We present a geometric approach to the field theory with higher order anisotropic interactions. The concepts of higher order space, or locally anisotropic, space (in brief, h-space, or la-space) are introduced as general ones for various types of higher order extensions of Lagrange and Finsler geometry and higher dimen…

We develop a general theory for irreducible homogeneous spaces M=G/HM= G/H, in relation to the nullity νν of their curvature tensor. We construct natural invariant (different and increasing) distributions associated with the nullity, that give a deep insight of such spaces. In particular, there must exist an order-two tr…
