This idea has been previously studied in Friedmann\u2013Robertson\u2013Walker (FRW) cosmology, where this \u201cnoncommutativity\u201d provides a simple mechanism that can explain the origin of the cosmological constant. In this paper, we obtain the same relationship between the cosmological constant and the deformation parameter that appears in deformed phase space cosmology, but in the context of the deformed phase space black holes. This was achieved by comparing the entropy of the deformed Schwarzschild black hole with the entropy of the Schwarzschild\u2013de Sitter black hole.<\/jats:p>","DOI":"10.3390\/e19030091","type":"journal-article","created":{"date-parts":[[2017,2,28]],"date-time":"2017-02-28T10:57:52Z","timestamp":1488279472000},"page":"91","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["On the Entropy of Deformed Phase Space Black Hole and the Cosmological Constant"],"prefix":"10.3390","volume":"19","author":[{"given":"Andr\u00e9s","family":"Crespo-Hern\u00e1ndez","sequence":"first","affiliation":[{"name":"Centro Universitario de la Ci\u00e9nega, Universidad de Guadalajara, Edificio P, Ocotl\u00e1n, Jalisco 47820, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eri","family":"Mena-Barboza","sequence":"additional","affiliation":[{"name":"Centro Universitario de la Ci\u00e9nega, Universidad de Guadalajara, Edificio P, Ocotl\u00e1n, Jalisco 47820, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Miguel","family":"Sabido","sequence":"additional","affiliation":[{"name":"Departamento de F\u00edsica de la Universidad de Guanajuato, Le\u00f3n 37150, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2017,2,28]]},"reference":[{"key":"ref_1","unstructured":"Polchinski, J.
