Abstract
We classify all complete uniform multipartite hypergraphs with respect to some algebraic properties, such as being (almost) complete intersection, Gorenstein, level, -Cohen-Macaulay, -Buchsbaum, unmixed, and satisfying Serre's condition , via some combinatorial terms. Also, we prove that for a complete -uniform -partite hypergraph , vertex decomposability, shellability, sequentially and sequentially Cohen-Macaulay properties coincide with the condition that has sides consisting of a single vertex. Moreover, we show that the latter condition occurs if and only if it is a chordal hypergraph.
