Spherically symmetric vacuum solution in Freund–Nambu scalar–tensor gravity
We present an exact solution in Freund–Nambu scalar–tensor gravity that extends the Janis–Newman–Winnicour (JNW) naked-singularity spacetime. The metric retains the JNW form governed by parameter n, while a new parameter q deforms the profile of the massive scalar field φ.\documentclass[12pt]{minimal} \usepackage{amsma...
