Some TurÃ¡n-type results for the signless Laplacian spectral radius

Jian Zheng, Yongtao Li, Yi-Zheng Fan

Half a century ago, BollobÃ¡s and ErdÅs [Bull. London Math. Soc. 5 (1973)] proved that every $n$ -vertex graph $G$ with $e (G) \geq (1 - \frac{1}{k} + ε) \frac{n ^{2}}{2}$ edges…

On Multilinear Forms for Mod $p$ Representations of $GL_{2} (Q_{p})$

Yikun Fan

Motivated by the study of trilinear forms for complex representations, we investigate the space of $G$ -invariant linear forms on tensor products of irreducible admissible represent…

Spectral TurÃ¡n problems for nondegenerate hypergraphs

Jian Zheng, Honghai Li, Yi-Zheng Fan

Keevash, Lenz and Mubayi developed a general criterion for hypergraph spectral extremal problems in their seminal work (SIAM J. Discrete Math., 2014). Their framework shows that ex…

The multiplicity of eigenvalues of nonnegative tensors and hypergraphs

Yi-Zheng Fan

Hu and Ye conjectured that for an $n$ -dimensional tensor $A$ of order $k$ with an eigenvalue $λ$ and the corresponding eigenvariety $V_{λ} (A)$ , the alge…
