Thermodynamic geometry of the Garfinkle–Horowitz–Strominger dilaton black hole

摘要: This paper studies the thermodynamic properties of Garfinkle–Horowitz–Strominger dilaton black hole from viewpoint geometry. It calculates heat capacity and temperature hole, Weinhold metric Ruppeiner are also obtained respectively. finds that they both curved scalar curvature geometry consists with first-order transition point reproduced capacity, while one is in accordance second-order phase points capacity.
