摘要：Considering the cosmological constantΛas a thermodynamic pressure and its conjugate quantity as a thermodynamic volume as proposed by Kubiznak and Mann[*** Energy Phys.1207(2012)033],we discuss the critical behavior of charged AdS black hole in arbitrary dimensions *** particular,we present a comparative study in terms of the spacetime dimension d and the displacement of critical points controlling the transition between the small and the large black *** behaviors vary nicely in terms of *** result shows that the equation of state for a charged Reissner–Nordstrom AdS black hole predicts an universal number given by(2d-5)/(4d-8).The three-dimensional solution is also discussed.

摘要：We reconsider the study of critical behaviors of Kerr—Newman Anti-de Sitter(AdS)black holes in four *** study is made in terms of the moduli space parameterized by the charge Q and the rotation parameter a,relating the mass M of the black hole and its angular momentum J via the relation a=J/***,we discuss such thermodynamical behaviors in the presence of a positive cosmological constant considered as a thermodynamic pressure and its conjugate quantity as a thermodynamic *** equation of state for a charged Reissner—Nordstrom AdS black hole predicts a critical universal number depending on the(Q,a)moduli *** the vanishing limit of the a parameter,this prediction recovers the usual universal number in four ***,we find the bounded region of the moduli space allowing the consistency of the model with real thermodynamical variables.
