Static charged black holes in (2+1)-dimensional dilaton gravity
Static charged black holes in (2+1)-dimensional dilaton gravity
A one parameter family of static charged black hole solutions in (2+1)-dimensional general relativity minimally coupled to a dilaton \ensuremath{\varphi}\ensuremath{\propto}ln(r/\ensuremath{\beta}) with a potential term ${\mathit{e}}^{\mathit{b}\mathrm{\ensuremath{\varphi}}}$\ensuremath{\Lambda} is obtained. Their causal structures are investigated, and the thermodynamical temperature and entropy are computed. One particular black hole in the family has the same …
