标题： Regular black hole solutions in $(2 + 1)$-dimensional $f(R,T)$ gravity coupled to nonlinear electrodynamics

摘要： 在本文中，我们研究了广义相对论和$f(R, T)$引力的(2+1)维版本中的规则黑洞解，这些解都与非线性电动力学耦合。 通过承认生成这些几何结构的物质内容满足麦克斯韦极限条件，我们获得了一类产生新解的规则黑洞，并成功再现了早期对(2+1)维广义相对论研究中的特定情况。 此外，我们在(2+1)维$f(R, T)$引力中发现了第一个规则黑洞解，并对这些解中存在的能量-动量张量的非守恒性进行了定性和定量的探索。 显示英文摘要

摘要： In this paper, we investigate regular black hole solutions in the (2+1)-dimensional versions of General Relativity and $f(R, T)$ gravity, both coupled to nonlinear electrodynamics. By admitting that the matter content that generates such geometries satisfies the Maxwell limit condition, we obtain a class of regular black holes that give rise to new solutions and successfully reproduce particular cases found in earlier studies of (2+1)-dimensional General Relativity. Moreover, we discover the first regular black hole solutions in (2+1)-dimensional $f(R, T)$ gravity and explore both qualitatively and quantitatively the non-conservation of the energy-momentum tensor present in those solutions.
