Spectral radius of graphs of given size with forbidden a fan graph $F_{6}$

Jing Gao, Xueliang Li

Let $F_{k} = K_{1} \lor P_{k - 1}$ be the fan graph on $k$ vertices. A graph is said to be $F_{k}$ -free if it does not contain $F_{k}$ as a subgraph. Yu et al. in [arXiv:2404.03423] conjectured…

The maximum spectral radius of $θ_{1, 3, 3}$ -free graphs with given size

Jing Gao, Xueliang Li

A graph $G$ is said to be $F$ -free if it does not contain $F$ as a subgraph. A theta graph, say $θ_{l_{1}, l_{2}, l_{3}}$ , is the graph obtained by connecting two distinct vertices with th…
