It has been shown by several authors that several such conditions are quasi-random, but that there are exceptions. In order to understand this better, we investigate some new properties of this type. We show that these properties too are quasi-random, at least in some cases; however, there are also cases that are left as open problems, and we discuss why the proofs fail in these cases. The proofs are based on the theory of graph limits; and on the method and results developed by Janson (2011), this translates the combinatorial problem to an analytic problem, which then is translated to an algebraic problem.", "revisions": [ { "version": "v1", "updated": "2014-05-27T06:40:10.000Z" } ], "analyses": { "subjects": [ "05C99" ], "keywords": [ "graph limits", "quasi-random graphs", "subgraph counts", "properties", "analytic problem" ], "note": { "typesetting": "TeX", "pages": 35, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2014arXiv1405.6808J" } } }
