These simplicial complexes are a higher-dimensional analogue of clique (or flag) complexes (case k=2) and they are a rich new class of simplicial complexes. We show that Dirac's theorem on chordal graphs has a higher-dimensional analogue in which graphs and clique complexes get replaced, respectively, by simplicial matroids and k-hyperclique complexes. We prove also a higher-dimensional analogue of Stanley's reformulation of Dirac's theorem on chordal graphs.11 pages; Annals of Combinatorics, to appearCombinatoricsCommutative Algebra05B35 (primary), 05C17 (secondary)Dirac's theorem on simplicial matroidstext
