Then $\\mathcal{C}_1 \\wedge \\mathcal{C}_2$ denotes the class of all finite ($\\sigma\\cup\\tau$)-structures whose $\\sigma$-reduct is from $\\mathcal{C}_1$ and whose $\\tau$-reduct is from $\\mathcal{C}_2$. We prove that when $\\mathcal{C}_1$ and $\\mathcal{C}_2$ are Ramsey,\u00a0then $\\mathcal{C}_1 \\wedge \\mathcal{C}_2$ is also Ramsey. We also discuss variations of this statement,\u00a0and give several examples of new Ramsey classes derived from those general results.<\/jats:p>","DOI":"10.37236\/2566","type":"journal-article","created":{"date-parts":[[2020,1,11]],"date-time":"2020-01-11T01:05:08Z","timestamp":1578704708000},"source":"Crossref","is-referenced-by-count":11,"title":["New Ramsey Classes from Old"],"prefix":"10.37236","volume":"21","author":[{"given":"Manuel","family":"Bodirsky","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"23455","published-online":{"date-parts":[[2014,5,9]]},"container-title":["The Electronic Journal of Combinatorics"],"original-title":[],"link":[{"URL":"https:\/\/www.combinatorics.org\/ojs\/index.php\/eljc\/article\/download\/v21i2p22\/pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.combinatorics.org\/ojs\/index.php\/eljc\/article\/download\/v21i2p22\/pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,1,17]],"date-time":"2020-01-17T10:59:45Z","timestamp":1579258785000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.combinatorics.org\/ojs\/index.php\/eljc\/article\/view\/v21i2p22"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014,5,9]]},"references-count":0,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2014,3,31]]}},"URL":"https:\/\/doi.org\/10.37236\/2566","relation":{},"ISSN":["1077-8926"],"issn-type":[{"value":"1077-8926","type":"electronic"}],"subject":[],"published":{"date-parts":[[2014,5,9]]},"article-number":"P2.22"}}
