We study four problems on uniform hypergraph. First, we present a streaming algorithm for two-coloring uniform hypergraphs with limited number of hyperedges. Second, we show relationships between four different geometric parameters of the embedding of a complete 3-uniform hypergraph in 3-dimensional space. Third, we present a compression scheme for uniform hypertrees, which are generalizations of trees. Finally, we present a data structure for succinctly storing a hyperedge of a complete uniform hypergraph in order to support membership queries in the bitprobe model.
