Contact CR $ \delta $-invariant: an optimal estimate for Sasakian statistical manifolds
AIMS MathematicsChen (1993) developed the theory of $ \delta $-invariants to establish novel necessary conditions for a Riemannian manifold to allow a minimal isometric immersion into Euclidean space. Later, Siddiqui et al.

Curvature and topology dependency of the cosmological spectra
Results in Physics, 2019 In this article we investigate dependency of two important cosmological random fields defined on spatial slices of the FLRW universe and their spectra on the geometry and topology of the background universe.
