On quarter-symmetric metric connection

1978
The quarter-symmetric connections on manifolds with affine connection have been defined and studied by \textit{S. Golab} [Tensor, New. Ser. 29, 249-254 (1975; Zbl 0308.53010)]. The most general form of these connections has been determined by \textit{K. Yano} and \textit{T. Imai} [ibid. 38, 13-18 (1982; Zbl 0504.53014)].

On pseudo concircular symmetric manifold admitting a type of quarter symmetric metric connection

2012
Let \((M_n,g,n>2)\) be a non-flat Riemannian manifold, \(\Omega\) the concircular curvature tensor and \(A\) a non-zero 1-form such that \(g(X,\rho) =A(X)\); \(X,\rho\) are vector fields. A pseudo concircular symmetric manifold is defined under some conditions for \(\Omega\) and \(A\). Let \(r\) be the scalar curvature.
