The edge spectral extremal problem for odd wheels in nonzero residue classes
Honghao Chen, Jing Gao, Shuchao Li
For a fixed integer , let be an odd wheel graph. The fixed-size spectral extremal problem aims to determine \[ \operatorname{spex}(m,W_{2k+1}):=\m…
Characterizing -minimizer graphs: given order and independence number
Jiaqi Zhang, Shuchao Li
For a given graph \( G \), let \( A(G) \), \( Q(G) \), and \( D(G) \) denote the adjacency matrix, signless Laplacian matrix, and diagonal degree matrix of \( G \), respectively. T…
Spectral extremal results on the -spectral radius of graphs without -minor
Xingyu Lei, Shuchao Li
An important theorem about the spectral Turán problem of was largely developed in separate papers. Recently it was completely resolved by Zhai and Lin [J. Comb. Theory, S…
Spectral extrema of graphs with fixed size: forbidden a fan graph, friendship graph or theta graph
Shuchao Li, Sishu Zhao, Lantao Zou
It is well-known that the Brualdi-Hoffman-Turán-type problem inquiries about the maximum spectral radius \( λ(G) \) of an \( F \)-free graph \( G \) with \( m \) edges. Let \( θ_{1…
