  Let $\mathbb{Q}_{k,n}$ be the set of the connected $k$-uniform weighted
hypergraphs with $n$ vertices, where $k,n\geq 3$. For a hypergraph $G\in
\mathbb{Q}_{k,n}$, let $\mathcal{A}(G)$, $\mathcal{L} (G)$ and $\mathcal{Q}
(G)$ be its adjacency tensor, Laplacian tensor and signless Laplacian tensor,
respectively. The spectral radii of $\mathcal{A}(G)$ and $\mathcal{Q} (G)$ are
investigated. Some basic properties of the $H$-eigenvalue, the
$H^{+}$-eigenvalue and the $H^{++}$-eigenvalue of $\mathcal{A}(G)$,
$\mathcal{L} (G)$ and $\mathcal{Q} (G)$ are presented. Several lower and upper
bounds of the $H$-eigenvalue, the $H^{+}$-eigenvalue and the
$H^{++}$-eigenvalue for $\mathcal{A}(G)$, $\mathcal{L} (G)$ and $\mathcal{Q}
(G)$ are established. The largest $H^{+}$-eigenvalue of $\mathcal{L} (G)$ and
the smallest $H^{+}$-eigenvalue of $\mathcal{Q} (G)$ are characterized. A
relationship among the $H$-eigenvalues of $\mathcal{L} (G)$, $\mathcal{Q} (G)$
and $\mathcal{A} (G)$ is also given.
