In　this　paper,　we　define　a　homogeneous　polynomial　for　a　general　hypergraph,　and　establish　a　remarkable　connection　between　clique　number　and　the　homogeneous　polynomial　of　a　general　hypergraph.　For　a　general　hypergraph,　we　explore　some　inequality　relations　among　spectral　radius,　clique　number　and　the　homogeneous　polynomial.　We　also　give　lower　and　upper　bounds　on　the　spectral　radius　of　a　general　hypergraph　in　terms　of　the　clique　number.　(C)　2020　Elsevier　Inc.　All　rights　reserved.
