The answer to the following question could be trivial!
Introduction:
Expander graph is a sparse graph that has strong connectivity properties.
In this book or here. Expanders are defined only for the graph case.
Question:
Are expander graph are defined for hypergraphs ? and if so, is there already known work in this direction ?
The new definition of expanders could be: That is $(G_n)$ will be sequence of hypergraph, where $|G_n|\rightarrow \infty $ as $n\rightarrow \infty $, and $\exists \epsilon\in \mathbb{R}^+$ such that $h(G_n)\geq \epsilon$
Any idea will be useful!
