A cubic identity for the Infeld-van der Waerden field and its application [PDF]
A cubic identity for the Infeld-van der Waerden field is found and its application to verifying an explicit formula for the spinor components of the metric connection is demonstrated.

A note on Kosmann-Lie derivatives of Weyl spinors [PDF]
Kosmann-Lie derivatives in the bundle of Weyl spinors are considered. It is shown that the basic spin-tensorial fields of this bundle are constants with respect to these derivatives.

On operator fields in the bundle of Dirac spinors [PDF]
Operator fields in the bundle of Dirac spinors and their conversion to spatial fields are considered. Some commutator equations are studied with the use of the conversion technique.

Lifts of Almost r-Contact and r-Paracontact Structures [PDF]
In this study, taking into considering lifting theory, we shall obtain both almost complex and paracomplex structures on the tangent bun- dle, based on almost Lorentzian r-contact and r-paracontact manifold.

Compact Osserman manifolds with neutral metric [PDF]
It is shown that if a compact four-dimensional manifold with metric of neutral signature is Jordan-Osserman, then it is either of constant sectional curvature or Ricci flat.

Some Characterizations for Curves by the Help Of Spherical Representations in the Galilean and Pseudo-Galilean Space [PDF]
In this paper, we focus on some characterizations for curves in the Galilean and Pseudo-Galilean space.
