Spectral extrema of 1-planar graphs with no short cycles or small cliques

Shuchao Li, Mingli Wang, Qin Zhao

The spectral Turán type problem, initiated by Nikiforov in 2007, aims to determine the graphs among -vertex -free graphs having maximum spectral radius. In this paper, we stu…

Connected triangle-free planar graphs whose second largest eigenvalue is at most 1

Kun Cheng, Shuchao Li

Let be the second largest eigenvalue of the adjacency matrix of a connected graph. In 2023, Li and Sun \cite{LiSun1} determined all the connected -minor fre…
