    On a contact Riemannian manifold of dimension \(n= 2m+ 1\), \(m\geq 1\), an affine connection called \(\varphi\)-connection is introduced and the properties of the connection on \(K\)-contact and Sasakian manifolds are studied. Some conditions for a compact Sasakian manifold of odd dimension \(n\geq 3\) to be conformal to a sphere and some special cases are considered. See also \textit{S. S. Pujar} and \textit{B. S. Waghe} [Bull. Calcutta Math. Soc. 90, 197-204 (1998; Zbl 0966.53027)].
