Abstract

This paper aims to study some semi-symmetric and curvature tensor conditions on α-Kenmotsu pseudo-metric manifolds. Some conditions of semi-symmetric, locally symmetric, and the Ricci semi-symmetric are considered on such manifolds. Also, the relationships between the M-projective curvature tensor and conformal curvature tensor, concircularly curvature tensor, and conharmonic curvature tensor are investigated. Finally, an example of α-Kenmotsu pseudo-metric structure is given.

Abstract

Bu makale α-Kenmotsu pseudo-metrik manifoldlar üzerinde bazı yarı simetrik ve eğrilik tensör şartlarını çalışmayı amaçlamaktadır. Bazı yarı-simetrik, lokal simetrik ve Ricci yarı-simetrik şartlar bu tür manifoldlar için göz önüne alınmıştır. Ayrıca, M-projektif eğrilik tensörü ile konformal eğrilik tensörü, konsirküler eğrilik tensörü ve konharmonik eğrilik tensörü arasındaki ilişkiler araştırılmıştır. Makale açıklayıcı bir α-Kenmotsu pseudo-metrik manifold örneği ile sonlandırılmıştır.
