Paper Title :
Geometrothermodynamics of The Cosmological Constant

Author :Maria N. Quevedo, Hernando Quevedo

Article Citation :Maria N. Quevedo ,Hernando Quevedo , (2017 ) " Geometrothermodynamics of The Cosmological Constant " , International Journal of Management and Applied Science (IJMAS) , pp. 21-24, Volume-3,Issue-6

Abstract : We study the properties of black holes with cosmological constant in the framework of geometrothermodynamics. We consider in particular the case of the Schwarzschild-anti-de-Sitter black hole, and show that the corresponding fundamental equation is a generalized homogeneous function only if the cosmological constant is assumed to be a thermodynamic variable. We analyze the geo- metric properties of the equilibrium space and show that the presence of the cosmological constant changes drastically the stability properties and the phase transition structure of the black hole. Keywords- Black holes, phase transitions, thermodynamics, geometrothermodynamics PACS numbers: 05.70.Ce; 05.70.Fh; 04.70.-s; 04.20.-q
