Moreover by using computer methods we improve lower and upper bounds for some other multicolor Ramsey numbers involving quadrilateral $C_4$. We consider $3$ and $4$-color numbers, our results improve known bounds.<\/jats:p>","DOI":"10.37236\/641","type":"journal-article","created":{"date-parts":[[2020,1,10]],"date-time":"2020-01-10T22:43:37Z","timestamp":1578696217000},"source":"Crossref","is-referenced-by-count":2,"title":["On some Ramsey Numbers for Quadrilaterals"],"prefix":"10.37236","volume":"18","author":[{"given":"Janusz","family":"Dybizba\u0144ski","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tomasz","family":"Dzido","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"23455","published-online":{"date-parts":[[2011,7,29]]},"container-title":["The Electronic Journal of Combinatorics"],"original-title":[],"link":[{"URL":"https:\/\/www.combinatorics.org\/ojs\/index.php\/eljc\/article\/download\/v18i1p154\/pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.combinatorics.org\/ojs\/index.php\/eljc\/article\/download\/v18i1p154\/pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,1,17]],"date-time":"2020-01-17T18:07:38Z","timestamp":1579284458000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.combinatorics.org\/ojs\/index.php\/eljc\/article\/view\/v18i1p154"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2011,7,29]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2011,1,5]]}},"URL":"https:\/\/doi.org\/10.37236\/641","relation":{},"ISSN":["1077-8926"],"issn-type":[{"value":"1077-8926","type":"electronic"}],"subject":[],"published":{"date-parts":[[2011,7,29]]},"article-number":"P154"}}
