Geometric Curvatures of Plane Symmetry Black Hole

Figure 6

The negative unified geometric curvature ℛ_𝐿 versus the charge 𝑄, including the logarithmic correction with 𝑁=1, 𝛼=√3/3, and 𝑆=100. The parameter 𝛾 is set to 1/2 (left), 5/6 (middle), and 3/2 (right), respectively. The divergence points are at 𝑄=±11.3756, ±11.2613, and ±11.0326.
