On Generalized Recurrent and Generalized Concircularly Recurrent Weyl Manifolds

Özet

In the present work, generalized recurrent and generalized concircularly recurrent Weylmanifolds are examined. Nearly quasi-Einstein Weyl manifolds are defined and it is proved thatif a generalized recurrent or generalized concircularly recurrent Weyl manifold admits a specialconcircular vector field, then the manifold is a nearly quasi-Einstein Weyl manifold. Also, someother results are presented.
