For this, we use the combinatorial approach to the topology of PL manifolds by means of a special kind of edge-colored graphs, called crystallizations. Within this representation theory, Bracho and Montejano introduced in 1987 a nonnegative numerical invariant, called the reduced complexity, for any closed $n$-dimensional PL manifold.\u00a0 Here we consider this invariant, and extend in this context the concept of average order\u00a0first introduced by Luo and Stong in 1993, and successively investigated by Tamura in 1996 and 1998. Then\u00a0 we obtain some\u00a0 classification\u00a0 results for\u00a0 closed connected smooth low-dimensional manifolds according to\u00a0 reduced complexity and average order. Finally, we answer to a question posed by Trout in 2013.<\/jats:p>","DOI":"10.37236\/7493","type":"journal-article","created":{"date-parts":[[2020,1,10]],"date-time":"2020-01-10T07:06:26Z","timestamp":1578639986000},"source":"Crossref","is-referenced-by-count":0,"title":["On Graph-Theoretical Invariants of Combinatorial Manifolds"],"prefix":"10.37236","volume":"26","author":[{"given":"Alberto","family":"Cavicchioli","sequence":"first","affiliation":[]},{"given":"Fulvia","family":"Spaggiari","sequence":"additional","affiliation":[]}],"member":"23455","published-online":{"date-parts":[[2019,7,5]]},"container-title":["The Electronic Journal of Combinatorics"],"original-title":[],"link":[{"URL":"https:\/\/www.combinatorics.org\/ojs\/index.php\/eljc\/article\/download\/v26i3p10\/7869","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.combinatorics.org\/ojs\/index.php\/eljc\/article\/download\/v26i3p10\/7869","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,1,17]],"date-time":"2020-01-17T04:11:57Z","timestamp":1579234317000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.combinatorics.org\/ojs\/index.php\/eljc\/article\/view\/v26i3p10"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,7,5]]},"references-count":0,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2019,7,4]]}},"URL":"https:\/\/doi.org\/10.37236\/7493","relation":{},"ISSN":["1077-8926"],"issn-type":[{"type":"electronic","value":"1077-8926"}],"subject":[],"published":{"date-parts":[[2019,7,5]]},"article-number":"P3.10"}}
