Extension principles for the Einstein Yang--Mills system
Junbin Li, Jinhua Wang
We prove the local existence theorem and establish an extension principle for the spherically symmetric Einstein Yang--Mills system (SSEYM) with data. This in addition implie…

Interior instability of naked singularities of a scalar field
Junbin Li
We show that the -self-similar naked singularity solutions of the spherically symmetric Einstein--Scalar field system are unstable to black hole formation under perturbations th…

Scalar perturbations to naked singularities of perfect fluid
Junbin Li, Xi-Ping Zhu
In this paper, we study the instability of naked singularities arising in the Einstein equations coupled with isothermal perfect fluid. We show that the spherically symmetric self-…
