Global and asymptotic properties of self-gravitating nonlinear sigma models
Oleksandr S. Stashko, Valery I. Zhdanov, Mark P. Hertzberg
We present an analytical study of the global and asymptotic properties of static, spherically symmetric, asymptotically flat solutions in general relativity and its \(D\)-dimension…

On the stability of spherically symmetric relativistic configurations with scalar field
Anatolii Tugay, Valery Zhdanov, Yurii Taistra
Static spherically symmetric asymptotically flat configurations in General Relativity with a minimally coupled scalar field typically possess naked singularities. We study a linear…
