A Necessary and Sufficient Condition on the Weyl Manifolds Admitting a   Semi Symmetric Non-Metric Connection to be S-Concircular
  The object of this paper is to obtain the concircular curvature tensor of the semi symmetric non-metric connection on the Weyl manifold and to give a necessary and sufficient condition for a semi symmetric non-metric connection to be S-concircular.
