Especially we focus on the radii of starlikeness, convexity, and uniform convexity of hyper-Bessel functions and we show that the obtained radii satisfy some transcendental equations. In addition, we give some bounds for the first positive zero of normalized hyper-Bessel functions, Redheffer-type inequalities, and bounds for this function. In this study we take advantage of Euler–Rayleigh inequalities and Laguerre–Pólya class of real entire functions, intensively.</dc:description><dc:publisher>Springer</dc:publisher><dc:date>2020</dc:date><dc:type>Article</dc:type><dc:identifier>https://rdlopen.rawdatalibrary.net/r/gumushane/14797</dc:identifier><dc:identifier>https://doi.org/10.1007/s11139-018-0105-9</dc:identifier><dc:identifier>1382-4090</dc:identifier><dc:language>en</dc:language><dc:relation>Ramanujan Journal</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/14797</dc:identifier></oai_dc:dc></metadata></record></GetRecord></OAI-PMH>
