First, we show that the Pell-Lucas-Eisenstein series are convergent on their domain. Afterwards we prove that they satisfy some certain functional equations. Proofs follows from some on calculations on Pell-Lucas numbers.  © 2022 World Scientific Publishing Company.</dc:description><dc:publisher>World Scientific</dc:publisher><dc:date>2022</dc:date><dc:type>Article</dc:type><dc:identifier>https://rdlopen.rawdatalibrary.net/r/ebyu/12688</dc:identifier><dc:identifier>https://doi.org/10.1142/s1793557122502199</dc:identifier><dc:identifier>1793-5571</dc:identifier><dc:language>en</dc:language><dc:relation>Asian-European Journal of Mathematics</dc:relation><dc:rights>info:eu-repo/semantics/openAccess</dc:rights><dc:type>info:eu-repo/semantics/article</dc:type><dc:identifier>https://ebyu-rdlopen.rawdatalibrary.net/tr/items/ebyu/12688</dc:identifier></oai_dc:dc></metadata></record></GetRecord></OAI-PMH>
