TY - JOUR T1 - SILVER STRUCTURES ON THE RIEMANN EXTENSIONS AU - Meriç, Şemsi Eken AU - Ocak, Filiz PY - 2024 DA - December Y2 - 2024 DO - 10.33773/jum.1567074 JF - Journal of Universal Mathematics JO - JUM PB - Gökhan ÇUVALCIOĞLU WT - DergiPark SN - 2618-5660 SP - 67 EP - 72 VL - 7 IS - To memory "Assoc. Prof. Dr. Zeynep AKDEMİRCİ ŞANLI" LA - en AB - In the present paper we deal with an $n-$dimensional differentiable manifold $M$ with a torsion-free linear connection $\nabla $. Here we study some properties of a silver structure on the cotangent bundle ${{T}^{*}}M$ equipped with the Riemannian extension ${{}^{R}}\nabla$ and obtain a necessary condition for which the silver semi-Riemannian manifold $\left( {{T}^{*}}M{{,}^{R}}\nabla ,S \right)$ to be a locally decomposable.
