Shadows of three black holes in static equilibrium configuration

Dan Li, Yuxiang Zuo, Shiyang Hu +3

In this paper, we employ a ray-tracing algorithm to simulate the shadows of three equal-mass black holes in static equilibrium across a wide parameter space. We find that the shado…

Extremal spectral radius and $g$ -good $r$ -component connectivity

Wenxiu Ding, Dan Li, Yu Wang

For $F \subseteq V (G)$ , if $G - F$ is a disconnected graph with at least $r$ components and each vertex $v \in V (G) \ F$ has at least $g$ neighbors, then $F$ is called a $g$ -go…
