The first result shows that there exists a language that can be generated by some dag-PCGS (PCGS with communication structures realizable by directed acyclic graphs) consisting of 3 grammars, but by no PCGS with tree communication structure. The second result shows that dag-PCGS have their communication complexity of language generation either constant or linear.<\/jats:p>","DOI":"10.3233\/fi-1996-253405","type":"journal-article","created":{"date-parts":[[2019,12,2]],"date-time":"2019-12-02T20:46:44Z","timestamp":1575319604000},"page":"271-284","source":"Crossref","is-referenced-by-count":0,"title":["TWO LOWER BOUNDS ON DISTRIBUTIVE GENERATION OF LANGUAGES"],"prefix":"10.1177","volume":"25","author":[{"given":"Juraj","family":"Hromkovi\u010d","sequence":"first","affiliation":[{"name":"Dept. of Mathematics & Informatics, University of Paderborn, 33098 Paderborn, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jarkko","family":"Kari","sequence":"additional","affiliation":[{"name":"Dept. of Mathematics, University of Turku and Academy of Finland, 20500 Turku, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lila","family":"Kari","sequence":"additional","affiliation":[{"name":"Dept. of Mathematics, University of Turku and Academy of Finland, 20500 Turku, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dana","family":"Pardubsk\u00e1","sequence":"additional","affiliation":[{"name":"Faculty of Mathematics and Physics, Comenius University, 84215 Bratislava, Slovakia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[1996,1,1]]},"container-title":["Fundamenta Informaticae"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.3233\/FI-1996-253405","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.3233\/FI-1996-253405","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T06:33:30Z","timestamp":1777444410000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.3233\/FI-1996-253405"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1996,1,1]]},"references-count":0,"journal-issue":{"issue":"3-4","published-print":{"date-parts":[[1996,3]]}},"alternative-id":["10.3233\/FI-1996-253405"],"URL":"https:\/\/doi.org\/10.3233\/fi-1996-253405","relation":{},"ISSN":["0169-2968","1875-8681"],"issn-type":[{"value":"0169-2968","type":"print"},{"value":"1875-8681","type":"electronic"}],"subject":[],"published":{"date-parts":[[1996,1,1]]}}}
