Isotropic Weyl manifold with a semi-symmetric connection

Acta Mathematica Scientia, 2009
Abstract In this work, it is proved that every isotropic Weyl manifold with a semi-symmetric connection is locally conformal to an Einstein manifold with a semi-symmetric connection.

Concircularly semi-symmetric metric connection

Quaestiones Mathematicae, 2023
Results on a concircularly semi-symmetric metric connection on a Riemannian manifold are presented. Six linearly independent curvature tensors with respect to this non-symmetric linear connection are studied, and the tensors coincident with the Weyl projective curvature  tensor and the concircular curvature tensor of the Levi-Civita connection are

On semi-symmetric connections

Periodica Mathematica Hungarica, 1990
Let \(\nabla\) be a linear connection on M (dim M\(>2)\) and \(\pi\) be a 1- form, R and T the curvature and torsion tensors of \(\nabla\). It is proved that: a) For a \(\pi\)-semisymmetric \(\nabla\) \((T(X,Y)=\pi (Y)X-\pi (X)Y)\) the following statements are equivalent: (i) \(d\pi =0\), \((ii)\quad \sigma_{(X,Y,Z)}\{R(X,Y)Z\}=0,\) \((iii)\quad ...
