Commutation Formulae With Respect to Non-Symmetric Affine Connection
Nenad O. Vesić, Dušan J. Simjanović
Commutation formulae with respect to a non-symmetric affine connection are obtained in this paper. The components of commutation formulae in this paper are covariant derivatives of…
Associated Derived Invariants for Geometric Mappings of Non-Symmetric Affine Connection Spaces
Nenad O. Vesić
The invariants of the Thomas and the Weyl type for a mapping between non-symmetric affine connection spaces are obtained with respect to the factored deformation tensor in this pap…
Cosmological Meaning of Geometric Curvatures
Nenad O. Vesić
In this paper, we analyzed the physical meaning of scalar curvatures for a generalized Riemannian space. It is developed the Madsen's formulae for pressures and energy-densities wi…
Linear Independence of Covariant Derivatives and Space-Curvatures
Nenad O. Vesić
It is developed the considerations from (S. M. Minčić, [14, 15]) about curvature tensors and pseudotensors for a non-symmetric affine connection space in this paper. How many kinds…
Einstein-Hilbert actions with torsion
Nenad O. Vesić, Dragoljub D Dimitrijević
In this paper, we studied the full Einstein-Hilbert actions with respect to non-symmetric metrics and the corresponding torsion. The first concrete result in this paper are the gen…
Invariants of Third Type Almost Geodesic Mappings of Generalized Riemannian Space
Nenad O. Vesić
We studied rules of transformations of Christoffel symbols under third type almost geodesic mappings in this paper. From this research, we obtained some new invariants of these map…
