Ellipsoidal Expansion of the Universe, Cosmic Shear, Acceleration and
  Jerk Parameter
  In order to study if the anisotropy of the spacetime may induce differences
in the cosmic shear or in deceleration parameter we investigate in Bianchi I
Universe the most general expression for the cosmic shear and we study the
connections between deceleration parameter and cosmic shear. We also consider a
shear parametric approach to measure the transition from decelerating to an
accelerating Universe. We also study the connection between jerk parameter and
ellipsoidal Universe.
