The unicyclic hypergraph with extremal spectral radius

Guanglong Yu, Lin Sun

For a $h y p er g r a p h$ $G = (V, E)$ consisting of a nonempty vertex set $V = V (G)$ and an edge set $E = E (G)$ , its $a d j a ce n cy$ $ma t r i x$ $\mathcal {A}_{\mathcal{…

Large $Y_{3, 2}$ -tilings in 3-uniform hypergraphs

Jie Han, Lin Sun, Guanghui Wang

Let $Y_{3, 2}$ be the 3-graph with two edges intersecting in two vertices. We prove that every 3-graph $H$ on $n$ vertices with at least $ \max \left \{ \binom{4αn}{3}, \binom{n…
