摘要:

本文的主要目的是分析线性电磁Maxwell场和非线性电磁Born-Infeld场共同作用下立方准拓扑引力的磁膜解。我们发现,上述磁解没有曲率奇异性,也没有地平线,但我们观察到,有一个圆锥几何与相关的赤字角。我们得到的度量函数和赤字角,并考虑他们的行为。我们证明了解的性质依赖于三次拟拓扑系数和Gauss-Bonnet参数。

英文摘要:

The main purpose of the present paper is analyzing magnetic brane solutions of cubic quasi-topological gravity in the presence of a linear electromagnetic Maxwell field and a nonlinear electromagnetic Born-Infeld field. We show that the mentioned magnetic solutions have no curvature singularity and also no horizons, but we observe that there is a conic geometry with a related deficit angle. We obtain the metric function and deficit angle and consider their behavior. We show that the attributes of our solution are dependent on cubic quasi-topological coefficient and the Gauss-Bonnet parameter.
