In the paper, the authors studied conformally symmetric Para-Sasakian manifolds and they proved that an n-dimensional conformally symmetric Para-Sasakian manifold is conformally flat and SP-Sasakian.

In this paper, we investigate lightlike hypersurfaces which are semi-symmetric, Ricci semi-symmetric, parallel or semi-parallel in a semi-Euclidean space. We obtain that every screen conformal lightlike hypersurface of the Minkowski spacetime is semi-symmetric.

Ribosomes position their substrate at stereochemistry suitable for peptide bond formation, and promote substrate-mediated cata-lysis. The linkage between substrate orientation, dominated by remote interactions, and a sizable symmetrical region identified in all known ribosome structures indicates a guided rotatory motion of aminoacylated-tRNAs along a ribosomal path leadings to the advance of nascent peptides into the protein exit tunnel at an extended conformation.

We study the problem of conformally deforming a metric to a prescribed symmetric function of the eigenvalues of the Ricci tensor. We prove an existence theorem for a wide class of symmetric functions on manifolds with positive Ricci curvature, provided the conformal class admits an admissible metric. 1. Introduction Let (M n , g) be a smooth, closed Riemannian manifold of dimension n.
