论文摘要
在Einstein-Yang-Mills-Dilaton理论的框架中获得并检查了带有球形对称性的静态黑洞。获得的黑洞溶液使我们得出并研究熵，温度和热容量。为了更好地检查黑洞扩展相空间的热力学。在这个基础上，获得并研究了状态方程。我们还研究了Gibbs自由能，并且显示在临界温度下方，系统显示了第一个和零体顺序的相变，这对于其他类型的Dilaton黑洞都是显着的特征。最后，计算了黑洞的临界指数。
A static black hole with spherical symmetry is obtained and examined in the framework of Einstein-Yang-Mills-dilaton theory. The obtained black hole solution allowed us to derive and investigate entropy, temperature and heat capacity. To better examine the thermodynamics of the black hole extended phase space is also used. On this ground the equation of state is obtained and studied. We have also investigated the Gibbs free energy and it is shown that below the critical temperature the system demonstrates phase transitions of the first as well as of the zeroth order which is notable feature for other types of dilaton black holes. At the end critical exponents for the black hole are calculated.
