We show that in the standard Hechler extension there is an unbounded real which is dominated by every dominating real, but that this fails to hold in the tree Hechler extension. We prove a representation theorem for dominating reals in the standard Hechler extension: every dominating real eventually dominates a sandwich composition of the Hechler real with two ground model reals that monotonically converge to infinity. We apply our results to negatively settle a conjecture of Brendle and L\u00f6we (Conjecture 15 of [4]). We also answer a question due to Laflamme.<\/jats:p>","DOI":"10.2178\/jsl.7801190","type":"journal-article","created":{"date-parts":[[2013,1,23]],"date-time":"2013-01-23T14:38:23Z","timestamp":1358951903000},"page":"275-289","source":"Crossref","is-referenced-by-count":3,"title":["Unbounded and dominating reals in Hechler extensions"],"prefix":"10.1017","volume":"78","author":[{"given":"Justin","family":"Palumbo","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2014,3,12]]},"reference":[{"key":"S0022481200000414_ref009","doi-asserted-by":"publisher","DOI":"10.2307\/421159"},{"key":"S0022481200000414_ref008","doi-asserted-by":"publisher","DOI":"10.1002\/malq.19940400208"},{"key":"S0022481200000414_ref007","doi-asserted-by":"publisher","DOI":"10.1090\/pspum\/013.2\/9987"},{"key":"S0022481200000414_ref006","unstructured":"Hamkins Joel David (mathoverflow.net\/users\/1946), Cantor-Bernstein for notions of forcing, MathOverflow, http:\/\/mathoverflow.net\/questions\/79323 (version: 2011-10-29)."},{"key":"S0022481200000414_ref005","first-page":"582","volume":"52","author":"Groszek","year":"1987","journal-title":"Combinatorics on ideals and forcing with trees"},{"key":"S0022481200000414_ref004","doi-asserted-by":"publisher","DOI":"10.2969\/jmsj\/06310137"},{"key":"S0022481200000414_ref002","first-page":"94","volume":"50","author":"Baumgartner","year":"1985","journal-title":"Adjoining dominating functions"},{"key":"S0022481200000414_ref001","doi-asserted-by":"crossref","DOI":"10.1201\/9781439863466","volume-title":"Set theory","author":"Bartoszy\u0144ski","year":"1995"},{"key":"S0022481200000414_ref011","doi-asserted-by":"publisher","DOI":"10.1016\/0168-0072(93)90037-E"},{"key":"S0022481200000414_ref012","first-page":"595","volume-title":"Logic Colloquium 76","volume":"87","author":"Truss","year":"1977"},{"key":"S0022481200000414_ref010","first-page":"439","volume-title":"Set theory of the reals","volume":"6","author":"Scheepers","year":"1993"},{"key":"S0022481200000414_ref003","doi-asserted-by":"publisher","DOI":"10.1016\/0168-0072(92)90027-W"}],"container-title":["The Journal of Symbolic Logic"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.cambridge.org\/core\/services\/aop-cambridge-core\/content\/view\/S0022481200000414","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,4,24]],"date-time":"2019-04-24T19:11:12Z","timestamp":1556133072000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.cambridge.org\/core\/product\/identifier\/S0022481200000414\/type\/journal_article"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2013,3]]},"references-count":12,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2013,3]]}},"alternative-id":["S0022481200000414"],"URL":"https:\/\/doi.org\/10.2178\/jsl.7801190","relation":{},"ISSN":["0022-4812","1943-5886"],"issn-type":[{"value":"0022-4812","type":"print"},{"value":"1943-5886","type":"electronic"}],"subject":[],"published":{"date-parts":[[2013,3]]}}}
