In this article we study two classes of contact metric three manifolds, where first we investigate the necessary and sufficient condition for the contact metric three manifold to be partially pseudo- Ricci-symmmetric manifold of constant type. We find also two relations that the 3-dimensional (k,m,n ) _ contact metric manifold has to satisfy to be partially pseudo- Ricci-symmetric manifold of constant type.
in this paper we: defined Riemannian spaces, conformal mappings, Einstein spaces, Riemannian symmetric spaces, Ricci spaces and Ricci symmetric spaces, recall the fundamental properties of these spaces
Stereoscopic broadcast Tv systems,That is,Those capable of reproducing a Three-dimensional picture,give a better idea about The televised scene,enhance artistic impression,and make The reproduction more realistic so That The observer has The sensatio n of being actually present at The scene of action. For a compatible 2-d/3-d colour Tv system The channel bandwidth should be twice That of The standard broadcast Tv channel. The search for ways and means of reducing The required bandwidth without an impairment in The quality of The colour 3-d picture is a major direction in work or such systems.
In this paper, we described tow parallel algorithms for finding the solution of symmetric pentadiagonal linear systems of equations of order n . The proposed algorithms require 2 processors; each of both possesses      N O n local memor y. The first algorithm includes writing the pentadiagonal matrix in the form of product of tow tridiagonal matrices. We suggested a parallel algorithm for solving tridiagonal linear systems of equations. The second algorithm consists of decomposition of the pentadiagonal matrix in a form such that we can carry out the resulting linear systems of equations by using parallel algorithm. We carried out many numerical experiments to illustrate the efficiency, speeding up and accuracy for solving symmetric pentadiagonal linear systems of equations. The numerical experiments showed that the proposed algorithms were efficient and one of both was much faster in factor of 2 than the other one for solving the same test problems.
