A bipartite graph $\\Gamma$ is distance-biregular when it is distance-regular around each vertex and the intersection array only depends on the stable set such a vertex belongs to. In this note we derive a new version of the spectral excess theorem for bipartite distance-biregular graphs.<\/jats:p>","DOI":"10.37236\/3305","type":"journal-article","created":{"date-parts":[[2020,1,10]],"date-time":"2020-01-10T20:23:49Z","timestamp":1578687829000},"source":"Crossref","is-referenced-by-count":3,"title":["The Spectral Excess Theorem for Distance-Biregular Graphs."],"prefix":"10.37236","volume":"20","author":[{"given":"Miquel \u00c0ngel","family":"Fiol","sequence":"first","affiliation":[]}],"member":"23455","published-online":{"date-parts":[[2013,8,16]]},"container-title":["The Electronic Journal of Combinatorics"],"original-title":[],"link":[{"URL":"https:\/\/www.combinatorics.org\/ojs\/index.php\/eljc\/article\/download\/v20i3p21\/pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.combinatorics.org\/ojs\/index.php\/eljc\/article\/download\/v20i3p21\/pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,1,17]],"date-time":"2020-01-17T06:16:01Z","timestamp":1579241761000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.combinatorics.org\/ojs\/index.php\/eljc\/article\/view\/v20i3p21"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2013,8,16]]},"references-count":0,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2013,7,19]]}},"URL":"https:\/\/doi.org\/10.37236\/3305","relation":{},"ISSN":["1077-8926"],"issn-type":[{"type":"electronic","value":"1077-8926"}],"subject":[],"published":{"date-parts":[[2013,8,16]]},"article-number":"P21"}}
