Thus, this article portrays in detail the insertion of the variable x, y and the imaginary unit i in the sequence of Leonardo. Nevertheless, the mathematical results from this process of complexification of these numbers are studied, correlating the mathematical evolution of that sequence.<\/jats:p>","DOI":"10.7546\/nntdm.2022.28.1.115-123","type":"journal-article","created":{"date-parts":[[2022,2,28]],"date-time":"2022-02-28T20:23:26Z","timestamp":1646079806000},"page":"115-123","source":"Crossref","is-referenced-by-count":5,"title":["Leonardo's bivariate and complex polynomials"],"prefix":"10.7546","volume":"28","author":[{"given":"Milena Carolina dos Santos","family":"Mangueira","sequence":"first","affiliation":[]},{"given":"Renata Passos Machado","family":"Vieira","sequence":"additional","affiliation":[]},{"given":"Francisco Regis Vieira","family":"Alves","sequence":"additional","affiliation":[]},{"given":"Paula Maria Machado Cruz","family":"Catarino","sequence":"additional","affiliation":[]}],"member":"4381","published-online":{"date-parts":[[2022,2,28]]},"container-title":["Notes on Number Theory and Discrete Mathematics"],"original-title":[],"deposited":{"date-parts":[[2022,2,28]],"date-time":"2022-02-28T20:23:27Z","timestamp":1646079807000},"score":1,"resource":{"primary":{"URL":"https:\/\/nntdm.net\/volume-28-2022\/number-1\/115-123\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,2,28]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2022,2,28]]},"published-print":{"date-parts":[[2022,3]]}},"URL":"https:\/\/doi.org\/10.7546\/nntdm.2022.28.1.115-123","relation":{},"ISSN":["1310-5132","2367-8275"],"issn-type":[{"value":"1310-5132","type":"print"},{"value":"2367-8275","type":"electronic"}],"subject":[],"published":{"date-parts":[[2022,2,28]]}}}
