Sağır and Güngör defined the superposition operator Pg by Pg(x) = (g(k, s, xks))∞k,s=1 for all real double sequences (xks) where g: N2 × R → R and gave continuity of the superposition operator acting from the double sequence spaces Lp into Lq for 1 ≤ p, q &lt; ∞. In this paper, we characterize the continuity of the superposition operator acting from Maddox double sequence spaces L(p) into L(q)where p = (pks) and q = (qks) are bounded double sequences of positive numbers.</dc:description><dc:publisher>Shiraz University</dc:publisher><dc:date>2017</dc:date><dc:type>Article</dc:type><dc:identifier>https://rdlopen.rawdatalibrary.net/r/gumushane/15262</dc:identifier><dc:identifier>https://doi.org/10.1007/s40995-017-0266-1</dc:identifier><dc:identifier>1028-6276</dc:identifier><dc:language>en</dc:language><dc:relation>Iranian Journal of Science and Technology, Transaction A: Science</dc:relation><dc:rights>info:eu-repo/semantics/closedAccess</dc:rights><dc:type>info:eu-repo/semantics/article</dc:type><dc:identifier>https://gumushane-rdlopen.rawdatalibrary.net/tr/items/gumushane/15262</dc:identifier></oai_dc:dc></metadata></record></GetRecord></OAI-PMH>
