论文摘要
我们在$（2+1）$尺寸中提供新的常规黑洞解决方案，并在能量动量张量中存在物质场，其核心是平坦的或（a）DS结构。由于常规黑洞的热力学的第一定律是通过物质领域的存在来修改的，因此我们提供了第一定律的新版本，其中定义了能量变化的局部定义，并且熵和温度与先前已知的文献一致。结果表明，局部能量定义和总能量重合的迹象的迹象。此外，在Infinite，通常的第一法$ DM = TDS $。结果表明，所用的形式主义有效地计算出$（2+1）$的常规黑洞的总能量，而能量动量张量中存在物质。后者表明，这种形式主义的潜在适用性可以计算出$ d \ ge 4 $尺寸的其他常规黑洞模型的质量。
We provide a new regular black hole solution in $(2+1)$ dimensions with presence of matter fields in the energy momentum tensor, having its core a flat or (A)dS structure. Since the first law of thermodynamics for regular black holes is modified by the presence of the matter fields, we provide a new version of the first law, where a local definition of the variation of energy is defined, and, where the entropy and temperature are consistent with the previously known in literature. It is shown that the signs of the variations of the local definition of energy and of the total energy coincide. Furthermore, at infinite, the usual first law $dM=TdS$ is recovered. It is showed that the formalism used is effective to compute the total energy of regular black holes in $(2+1)$ with presence of matter in the energy momentum tensor. This latter suggests the potential applicability of this formalism to calculate the mass of other models of regular black holes in $d \ge 4$ dimensions.
