In this paper, two applications of concircular
mappings on the Weyl manifolds are given: Firstly, a necessary and sufficient
condition for an Einstein-Weyl manifold to be concircularly Ricci-flat is
obtained. Secondly, after defining a special type of semi-symmetric non-metric
connection which is called S -concircular, some properties of the Weyl manifold
with a vanishing curvature tensor with respect to such a connection are
examined.

Bu çalışmada, Weyl manifoldları üzerindeki
concircular tasvirlerin iki uygulaması verilmiştir: İlk olarak, Einstein-Weyl
manifoldunun concircular Ricci düz olabilmesi için bir gerek-yeter şart elde
edilmiştir. Daha sonra da, S -concircular olarak adlandırılan özel tipteki bir
yarı simetrik non-metrik konneksiyon tanımlanarak, böyle bir konneksiyona göre
sıfırlanan eğrilik tensörüne sahip Weyl manifoldunun bazı özellikleri
incelenmiştir
