摘要：

In light of the growing interest in the Hayward black hole solution, a detailed study on the corresponding lapse function and its roots is presented. The lapse function is expressed in terms of the classical Schwarzschild radius r(s) and the Hayward's parameter l. Both of these quantities are used as thermodynamic variables to find related thermodynamic quantities. In this context, the variable l is associated with a canonical conjugate variable F-H, and a free energy Xi. Moreover, a second order phase transition is found to appears at l approximate to 0.333r(s).
