Chew &amp; Lee [4] and Petranuarat &amp; Kemprasit [7] have characterized Pg : lp → l1 and Pg : lp → lq where 1 ≤ p; q &lt; ∞, respectively. The main goal of this paper is to construct the necessary and sucient conditions for the continuity of Pg : Lp → L1 and Pg : Lp → Lq where 1 _ p; q &lt; ∞.</dc:description><dc:publisher>University of Nis</dc:publisher><dc:date>2015</dc:date><dc:type>Article</dc:type><dc:identifier>https://rdlopen.rawdatalibrary.net/r/gumushane/15469</dc:identifier><dc:identifier>https://doi.org/10.2298/fil1509107s</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://gumushane-rdlopen.rawdatalibrary.net/tr/items/gumushane/15469</dc:identifier></oai_dc:dc></metadata></record></GetRecord></OAI-PMH>
