third order differential subordination and superordination results for analytic functions involving the Srivastava attiya operator
arXiv: Complex Variables, 2018Co-Authors: H M Srivastava, A Prajapati, P GochhayatAbstract:In this article, by making use of the linear operator introduced and studied by Srivastava and Attiya \cite{Srivastava1}, suitable classes of admissible functions are investigated and the dual properties of the third-order differential subordinations are presented. As a consequence, various sandwich-type theorems are established for a class of univalent analytic functions involving the celebrated Srivastava-Attiya transform. Relevant connections of the new results are pointed out.

some umbral calculus presentations of the chan chyan Srivastava polynomials and the erkuș Srivastava polynomials
Proyecciones (antofagasta), 2014Co-Authors: H M Srivastava, Kottakkaran Sooppy Nisar, Mumtaz Ahmad KhanAbstract:In their recent investigation involving differential operators for the generalized Lagrange polynomials, Chan et. al. [3] encountered and proved a certain summation identity and several other results for the Lagrange polynomials in several variables, which are popularly known in the literature as the Chan-Chyan-Srivastava polynomials. These multivariable polynomials have been studied systematically and extensively in the literature ever since then (see, for example, [1], [4], [9], [11], [12] and [13]). In the present paper, we investigate umbral calculus presentations ofthe Chan-Chyan-Srivastava polynomials and also of their substantially more general form, the Erkus-Srivastava polynomials [9]. Some other closely-related results are also considered.

a potential including the heaviside function in the 1 1 dimensional hydrodynamics by landau its basic properties and application to data at rhic energies
European Physical Journal A, 2009Co-Authors: T. Mizoguchi, H. Miyazawa, Minoru BiyajimaAbstract:In the 1 + 1 dimensional hydrodynamics originally proposed by Landau, we derive a new potential and distribution function including the Heaviside function and investigate their mathematical and physical properties. Using the original distribution derived by Landau, a distribution function found by Srivastava et al., our distribution function, and the Gaussian distribution proposed by Carruthers et al.. we analyze the data of the rapidity distribution on charged pious and K mesons at RHIC energies ( s NN = 62.4 GeV and 200 GeV). Three distributions derived from the hydrodynamics show almost the same chi-squared values provided the CERN MINUIT is used. We know that our calculations of hadron's distribution do not strongly depend on the range of integration of fluid rapidity, contrary to that of Srivastava et al. Finally, the roles of the Heaviside function in concrete analyses of data are investigated.

Applied Mathematics and Computation, 2008Co-Authors: Janusz SokolAbstract:Abstract Carlson and Shaffer [B.C. Carlson, D.B. Shaffer, Starlike and prestarlike hypergeometric functions, SIAM J. Math. Anal. 15 (1984) 737–745] have introduced a linear operator associated with the Gaussian hypergeometric function which has been generalized by Dziok and Srivastava [J. Dziok, H.M. Srivastava, Classes of analytic functions associated with the generalized hypergeometric function, Appl. Math. Comput. 103 (1999) 1–13]. Certain classes of analytic functions defined by means of those operators have been considered in [J. Dziok, H.M. Srivastava, Certain subclasses of analytic functions associated with the generalized hypergeometric function, Integral Transform. Spec. Funct. 14 (2003) 7–18; J. Dziok, H.M. Srivastava, Some subclasses of analytic functions with fixed argument of coefficients associated with the generalized hypergeometric function, Adv. Stud. Contemp. Math. 5 (2) (2002) 115–125] and recently in [J. Dziok, On some applications of the Briot–Bouquet differential subordination, J. Math. Anal. Appl. 328 (2007) 295–301; J. Dziok, Some relations including various linear operators, Demonstratio Math. XL (2007) 77–84; J.-L. Liu, H.M. Srivastava, Certain properties of the Dziok–Srivastava operator, Appl. Math. Comput. 159 (2004) 485–493]. In the present paper, new results for a familiar class of multivalent functions have been obtained. We have used the methods of differential subordination and the properties of Hadamard product.
