Partial sums of generalized Struve functions [PDF]

open access: yesMiskolc Mathematical Notes, 2016
Let (f(v, d, c))(n) (z) = z + Sigma(n)(k=1) b(k)z(k+1) be the sequence of partial sums of generalized and normalized Struve functions f(v, d, c) (z) = z + Sigma(infinity)(k=1) b(k)z(k+1) where b(k) = (-c/4)(k)/(3/2)(k)(F)(k) and F := v + (d+2)/2 not equal 0, -1, -2, .... The purpose of the present paper is to determine lower bounds for R{f(v, d, c) (z)/

The Struve-Sahade effect in the optical spectra of O-type binaries I. Main-sequence systems [PDF]

open access: yes, 1999
We present a spectroscopic analysis of four massive binary systems that are known or are good candidates to display the Struve-Sahade effect (defined as the apparent strengthening of the secondary spectrum of the binary when the star is approaching, and ...

On some properties of generalized Struve function

open access: goldCommunications Faculty Of Science University of Ankara Series A1Mathematics and Statistics, 2019
The main purpose of this investigation is to present some monotonic and log-concavity properties of the generalized Struve function. By using Hadamard product representation of the generalized Struve function, we investigate the sign of this function on some sets. Also, we determine an interval such that the generalized Struve function is decreasing in

Composition Formula for Saigo Fractional Integral Operator Associated with V-Function

open access: yesJournal of Mathematics, 2022
In this study, we form integral formulas for Saigo’s hypergeometric integral operator involving V-function. Corresponding assertions for the classical Riemann–Liouville (R-L) and Erdélyi–Kober (E-K) fractional integral operator are extrapolated. Also, by

Partial Sums of the Normalized Le Roy-Type Mittag-Leffler Function

open access: yesAxioms, 2023
Recently, some researchers determined lower bounds for the normalized version of some special functions to its sequence of partial sums, e.g., Struve and Dini functions, Wright functions and Miller–Ross functions. In this paper, we determine lower bounds

Integral representations and summations of the modified Struve function [PDF]

open access: yesActa Mathematica Hungarica, 2013
It is known that Struve function $\mathbf H_ν$ and modified Struve function $\mathbf L_ν$ are closely connected to Bessel function of the first kind $J_ν$ and to modified Bessel function of the first kind $I_ν$ and possess representations through higher transcendental functions like generalized hypergeometric ${}_1F_2$ and Meijer $G$ function.
