Black Holes and Two-Dimensional Dilaton Gravity

TL;DR

This paper investigates the conditions under which two-dimensional dilaton gravity models can dynamically form black holes and provides a comprehensive classification and parametric solutions for these black holes.

Contribution

It systematically characterizes all 2D dilaton gravity models capable of black hole formation and derives their general solutions.

Findings

Identified conditions for black hole formation in 2D dilaton gravity

Constructed a complete set of models with dynamical black holes

Provided parametric forms of the general black hole solutions

Abstract

We study the conditions for 2-dimensional dilaton gravity models to have dynamical formation of black holes and construct all such models. Furthermore we present a parametric representation of the general solutions of the black holes.
