Stability Analysis of Normal DGP Brane-world Model with Agegraphic Dark Energy
The aim of this work is to apply the dynamical system approach to study the linear dynamics of normal DGP brane-world model with agegraphic dark energy as the dark energy component. The stability analysis of the model will be investigated and phase plane portrait will be shown. The nature of critical points will be analyzed by evaluating the eigenvalues of linearized Jacobi matrix. Also, statefinder diagnostic procedure will be applied to compare deviation from {\Lambda}CDM model. One of the most interesting results of this work is the great alleviation of the coincidence problem.
The structure of GMA is introduced. Static displacement-force model and magnetism-machine coupling model for helping understand the magnetostriction and establishes simulation model are given. Simulation result shows that response time of machine part is slowness. It brings some disbennifit affection if minish damp. For example,exceed quantity and undulation will argument. It is important to ameliorate dynamic characteristic of the system to append a reasonable adjustor.
