Homogeneous geodesics in homogeneous Finsler spaces [PDF]
Journal of Geometry and Physics, 2007 In this paper, we study homogeneous geodesics in homogeneous Finsler spaces. We first give a simple criterion that characterizes geodesic vectors. We show that the geodesics on a Lie group, relative to a bi-invariant Finsler metric, are the cosets of the one-parameter subgroups.

The existence of light-like homogeneous geodesics in homogeneous Lorentzian manifolds [PDF]
Math. Nachr. 288, 8-9 (2015), 872-876, 2012 In previous papers, a fundamental affine method for studying homogeneous geodesics was developed. Using this method and elementary differential topology it was proved that any homogeneous affine manifold and in particular any homogeneous pseudo-Riemannian manifold admits a homogeneous geodesic through arbitrary point.

On homogeneous warped product Einstein metrics [PDF]
, 2014 In this article we study homogeneous warped product Einstein metrics and its connections with homogeneous Ricci solitons. We show that homogeneous $(\lambda,n+m)$-Einstein manifolds (which are the bases of homogeneous warped product Einstein metrics) are one-dimensional extensions of algebraic solitons. This answers a question from a paper of C. He, P.

Lorentzian homogeneous spaces admitting a homogeneous structure of type T1+T3 [PDF]
J.Geom.Phys. 56 (2006) 754-761, 2005 We show that a Lorentzian homogeneous space admitting a homogeneous structure of type T1 + T3 is either a (locally) symmetric space or a singular homogeneous plane wave.

Two-body binding energy calculation using homogeneous and inhomogeneous Lippmann-Schwinger equations within three-dimensional approach [PDF]
Iranian Journal of Physics Research, 2022 Bound state equations are mostly solved in partial-wave truncated basis. In partial-wave method, we need to consider many partial waves to reach the accurate results.

Synthesis of novel phthalimido oxime pseudoesters and evaluation of their cytotoxicity [PDF]
Journal of the Serbian Chemical Society, 2020 A series of novel optically pure oxime pseudoesters derivatives were synthesized by the reaction of substitute keto oximes with various N-substituted α-amino acids chlorides in the presence of triethylamine and dichloromethane at 0°C, and their ...

NH-HAZE: An Image Dehazing Benchmark with Non-Homogeneous Hazy and Haze-Free Images [PDF]
2020 IEEE/CVF Conference on Computer Vision and Pattern Recognition Workshops (CVPRW), 2020 Image dehazing is an ill-posed problem that has been extensively studied in the recent years. The objective performance evaluation of the dehazing methods is one of the major obstacles due to the lacking of a reference dataset.
