Coincidence Problem in an Oscillating Universe
Guangcan Yang, Anzhong Wang
We analyze an oscillating universe model in brane world scenario. The oscillating universe cycles through a series of expansions and contractions and its energy density is dominate…
On Gauge Choice of Spherically Symmetric 3-Branes
Anzhong Wang
Gauge choice for a spherically symmetric 3-brane embedded in a D-dimensional bulk with arbitrary matter fields on and off the brane is studied. It is shown that Israel's junction c…
Kink Stability of Self-Similar Solutions of Scalar Field in 2+1 Gravity
Anzhong Wang, Yumei Wu
The kink stability of self-similar solutions of a massless scalar field with circular symmetry in 2+1 gravity is studied, and found that such solutions are unstable against the kin…
Gravitational Collapse of Circularly Symmetric Stiff Fluid with Self-Similarity in 2+1 Gravity
A. Y. Miguelote, N. A. Tomimura, Anzhong Wang
Linear perturbations of homothetic self-similar stiff fluid solutions, , with circular symmetry in 2+1 gravity are studied. It is found that, except for those with an…
Kink Stability of Isothermal Spherical Self-Similar Flow Revisited
Anzhong Wang, Yumei Wu
The problem of kink stability of isothermal spherical self-similar flow in newtonian gravity is revisited. Using distribution theory we first develop a general formula of perturbat…
Asymptotics of Solutions of a Perfect Fluid Coupled with a Cosmological Constant in Four-Dimensional Spacetime with Toroidal Symmetry
Gregory A. Benesh, Anzhong Wang
Asymptotics of solutions of a perfect fluid when coupled with a cosmological constant in four-dimensional spacetime with toroidal symmetry are studied. In particular, it is found t…
