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…

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…
