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…
Spherically symmetric configurations in the quadratic gravity
V. I. Zhdanov, O. S. Stashko, Yu. V. Shtanov
We study spherically symmetric configurations of the quadratic gravity in the Einstein frame. In case of a purely gravitational system, we have determined the global qualita…
Singularities in static spherically symmetric configurations of General Relativity with strongly nonlinear scalar fields
O. S. Stashko, V. I. Zhdanov
There are a number of publications on relativistic objects dealing either with black holes or naked singularities in the center. Here we show that there exist static spherically sy…
