“…After a long interval, Yano [13] started the systematic study of semi-symmetric metric connection on a Riemannian manifold in 1970. In this connection, the properties of semi-symmetric metric connection are studied in ( [5], [19], [25], [27], [30], [36], [40], [42], [43], [48]) and others. P. Zhao and H. Song [21] defined and studied a projective semi-symmetric connection on Riemannian manifold in 2001.…”
