摘要
Abstract
Simple three-dimensional Einstein-scalar gravity is constructed in the present work,its black hole solution is found on condition of ()=2aφ(a is a constant). Further analysis reveals some similarities of this black hole to Reissner -Nordstrom black hole, but the mass of this black hole could be negative with α＞2e. Further, the Hawking temperature and Bekenstein-Hawking entropy of this black hole satisfy the laws of thermodynamics, and defines the internal energy of this black hole with a well-defined zero temperature limit. A comparison of the metric of this black solution with Reissner -Nordstrom metric reveals that a2 and l/l correspond to the mass and charge of the Reissner -Nordstrom black hole respectively.关键词
