Abstract

In the original language

We study the influence of scalar fields on a specific model of nonlinear electrody-namics (the square root Lagrangian) spacetime. We show that the singular horizoncreated by scalar field in spherically symmetric static scalar-vacuum spacetimes isstill present when nonlinear electrodynamics is added. For the obtained solution, we investigate the timelike geodesic motions of a test particle by studying the effective potential.
