As an example, the Birkhoff polytope, also known as the polytope of real doubly-stochastic matrices, has a unimodal $h^*$-vector, but when even small modifications are made to the polytope, the same property can be very difficult to prove. In this paper, we examine the $h^*$-vectors of a class of polytopes containing real doubly-stochastic symmetric matrices.", "revisions": [ { "version": "v1", "updated": "2014-09-09T13:58:04.000Z" } ], "analyses": { "subjects": [ "05A15", "52B20" ], "keywords": [ "symmetric doubly-stochastic matrices", "ehrhart series", "polytopes containing real doubly-stochastic symmetric", "containing real doubly-stochastic symmetric matrices" ], "note": { "typesetting": "TeX", "pages": 10, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2014arXiv1409.2742D" } } }
