Abstract:

In this talk, we study the instability of naked singularities arising in the Einstein equations coupled with an isothermal perfect fluid. We show that the spherically symmetric self-similar naked singularities of this system, are unstable to trapped surface formation, under C^{1,α} perturbations of an external massless scalar field. This is a joint work with Junbin Li.
