Brownian Motion in Minkowski Space

open access: yesEntropy, 2015
We construct a model of Brownian motion in Minkowski space. There are two aspects of the problem. The first is to define a sequence of stopping times associated with the Brownian “kicks” or impulses.

New Generalization of Geodesic Convex Function

open access: yesAxioms, 2023
As a generalization of a geodesic function, this paper introduces the notion of the geodesic φE-convex function. Some properties of the φE-convex function and geodesic φE-convex function are established.

Fermions in geodesic Witten diagrams [PDF]

open access: yesJournal of High Energy Physics, 2018
A bstractWe develop the embedding formalism for odd dimensional Dirac spinors in AdS and apply it to the (geodesic) Witten diagrams including fermionic degrees of freedom.

Geodesic stability, the space of rays and uniform convexity in Mabuchi geometry [PDF]

open access: yes, 2018
We establish the essentially optimal form of Donaldson's geodesic stability conjecture regarding existence of constant scalar curvature K\"ahler metrics.

Conservation Laws and Moving Frame Method of Vaidya-Bonner Space-Time [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2022
In the present paper, we compute the conservation laws  of the Vaidya-Bonner geodesic space-time metric in aRiemannian space and carry out the moving frame  method for this metric.

Anatomy of geodesic Witten diagrams [PDF]

open access: yes, 2017
A bstractWe revisit the so-called “Geodesic Witten Diagrams” (GWDs) [1], proposed to be the holographic dual configuration of scalar conformal partial waves, from the perspectives of CFT operator product expansions.

Integrability of Geodesics of Totally Geodesic Metrics [PDF]

open access: yes, 2019
Analysis of the geodesics in the space of signature $(1,3)$ that splits in two-dimensional distributions resulting from the Weyl tensor eignespaces - hyperbolic and elliptic ones - described in [V. Lychagin, V. Yumaguzhin, \emph{Differential invariants and exact solutions of the Einstein equations}, Anal.Math.Phys.

Spinning geodesic Witten diagrams [PDF]

open access: yes, 2017
A bstractWe present an expression for the four-point conformal blocks of symmetric traceless operators of arbitrary spin as an integral over a pair of geodesics in Anti-de Sitter space, generalizing the geodesic Witten diagram formalism of Hijano et al. [

Geodesic interpolation for reaction pathways.

open access: yesJournal of Chemical Physics, 2019
The development of high throughput reaction discovery methods such as the ab initio nanoreactor demands massive numbers of reaction rate calculations through the optimization of minimum energy reaction paths. These are often generated from interpolations

Construction of Developable Surface with Geodesic or Line of Curvature Coordinates

open access: yesJournal of New Theory, 2021
In this paper, a developable surface with geodesic or line of curvature coordinates is constructed in the Euclidean 3-space. A developable surface is coordinated by two families of parametric curves, base curves (directrices) and lines (rulings).
