This study looks into the bislant submanifolds of almost product semi-Riemannian manifolds that are Riemannian, semi-Riemannian and lightlike. We also state the theorems that provide the required conditions for constructing a slant submanifold from a bislant submanifold. Morever, we define the semi-slant submanifolds of locally product semi-Riemannian manifolds and discuss the integrability conditions of distributions that are invariants or slants that constitute a semi-slant submanifold.

Yarı-Riemannian Manifoldların Bislant ve Yarı-Slant Altmanifoldları İçin Bazı Sonuçlar

Öz

Bu çalışma hemen hemen çarpım yarı-Riemann manifoldların Riemann, yarı-Riemann ve ışıkbenzer olan bislant altmanifoldlarını incelemektedir. Ayrıca, bir bislant altmanifoldundan bir slant altmanifold oluşturmak için gerekli koşulları sağlayan teoremleri ifade ediyoruz. Dahası, lokal çarpım yarı-Riemann manifoldlarının yarı-slant altmanifoldlarını tanımlıyor ve yarı-slant bir altmanifold oluşturan değişmez veya slant dağılımların integrallenebilirlik koşullarını tartışıyoruz.
