# What is the definition of l-partite r-uniform hypergraph?

For example, if $G=A\cup B\cup C\cup D$ is a complete 4-partite 3-uniform hypergraph, is $a_1a_2b$ an edge (where $a_1,a_2\in A, b\in B$)?

Your question appears to be not really about uniformity: you simply want to know what a k-partite hypergraph is. And I think google and the likes should be able to answer that question. Did you try that? –  Thierry Zell Apr 9 '11 at 22:41
I did try google and I found both possible definitions being used. So I'd like to know whether there is a standard definition. –  Ping Apr 11 '11 at 1:34
