Novel Invariants for Almost Geodesic Mappings of the Third Type
Dušan J. Simjanović, Nenad O. Vesić
Two kinds of invariance for geometrical objects under transformations are involved in this paper. With respect to these kinds, we obtained novel invariants for almost geodesic mapp…

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…
