Strong spectral stabilities for -free graphs
Lantao Zou, Yongtao Li, Yuejian Peng
A stability result due to Ren, Wang, Wang and Yang [SIAM J. Discrete Math. 38 (2024)] shows that if and , and is a -free graph on $…
An edge-spectral Erdős-Stone-Simonovits theorem and its stability
Yongtao Li, Hong Liu, Shengtong Zhang
We study the extremal problem that relates the spectral radius of an -free graph with its number of edges. Firstly, we prove that for any graph with chromatic num…
A spectral Erdős-Rademacher theorem
Yongtao Li, Lu Lu, Yuejian Peng
A classical result of Erdős and Rademacher (1955) indicates a supersaturation phenomenon. It says that if is a graph on vertices with at least $\lfloor {n^2}/{4} \rfloor +1…
Spectral extremal graphs for fan graphs
Loujun Yu, Yongtao Li, Yuejian Peng
A well-known result of Nosal states that a graph with edges and contains a triangle. Nikiforov [Combin. Probab. Comput. 11 (2002)] extended this result to…
