For functions belonging to the class Nh,p∑ (λ,μ), we obtain estimates on the first two Taylor-Maclaurin coefficients |a2| and |a3|. The results presented in this paper would generalize and improve some recent works of Çaǧlar et al. [3], Xu et al. [10], and other authors.</dc:description><dc:publisher>UNIV NIS, FAC SCI MATH</dc:publisher><dc:date>2013</dc:date><dc:type>Article</dc:type><dc:identifier>https://rdlopen.rawdatalibrary.net/r/ebyu/15928</dc:identifier><dc:identifier>https://doi.org/10.2298/fil1305831s</dc:identifier><dc:identifier>0354-5180</dc:identifier><dc:language>en</dc:language><dc:relation>Filomat</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/15928</dc:identifier></oai_dc:dc></metadata></record></GetRecord></OAI-PMH>
