A spanning a tree of a graph G is a subgraph T, that is a tree, and contains every vertex of $G$.

Define a hypergraph as a collection of nodes, and hyperedges, where hyperedges are collections of nodes that are grouped together. (Collections of size 2 are just edge).

A hypertree is a hypergraph that is connected and doesn't contain hyperedge cycles (that is a collection of hyper edges that loops around through the same sets of vertices).

A spanning hypertree of a hypergraph G,is simply a sub-hypergraph T, that is a hypertree and contains all the nodes of G.
