Radius of α-Spirallikeness of Order cos(α)/2 for Entire Functions
MathematicsWe determine the radius of α-spirallikeness of order cos(α)/2 for entire functions represented as infinite products of their positive zeros. The discussion includes several examples featuring special functions such as Gamma functions, Bessel functions ...

Redheffer type inequalities for modified Bessel functions
Arab Journal of Mathematical Sciences, 2016 In this short note, we give new proofs of Redheffer’s inequality for modified Bessel functions of first kind published by Ling Zhu (2011). In addition, using the Grosswald formula we prove new Redheffer type inequality for the modified Bessel functions ...

The Bessel-Struve intertwining operator on ℂ and mean-periodic functions
International Journal of Mathematics and Mathematical Sciences, 2004 We give a description of all transmutation operators from the Bessel-Struve operator to the second-derivative operator. Next we define and characterize the mean-periodic functions on the space ℋ of entire functions and we characterize the continuous ...

On the Regular Integral Solutions of a Generalized Bessel Differential Equation
Advances in Mathematical Physics, 2018 The original Bessel differential equation that describes, among many others, cylindrical acoustic or vortical waves, is a particular case of zero degree of the generalized Bessel differential equation that describes coupled acoustic-vortical waves.
