In this paper, we introduce a new class of two-fold symmetric functions analytic in the unit disc. We prove such results as subordination and superordination properties, convolution properties, distortion theorems, and inequality properties of this new cl... see more

In this paper, we study the relative approximate controllability of nonlinear fractional stochastic evolution equations with time delays and nonlocal conditions, in Hilbert space, via new fixed point analysis approach. An example is provided to show the a... see more

In this paper, we prove the equivalence between the convergences of T-Picard iteration, T-Mann iteration and T-Ishikawa iteration for the class ofT-Zamfirescu operators in normed linear spaces. Our results extend and improvethe results of Solutz  and... see more

The main aim of this survey is to present some classical as well asrecent characterizations involving the notion of proximinal and Chebyshev sets inBanach spaces. In particular, we discuss the convexity of Chebyshev sets.

In the paper, the authors establish some new Hermite-Hadamard type integral inequalities when the power of the absolute value of the first derivative of the integrand is preinvex.

In this paper, we introduce some new subclasses of multivalent analytic functions in the unit disc E, and investigate a number of inclusion relationships, radius problem,  and some other interesting properties of p-valent functions which are defined ... see more

The aim of this paper is to establish a decay estimate for viscosity solutions of nonlinear PDEs. As an application we prove existence and uniqueness for time almost periodic viscosity solutions.

In this paper, we prove various existence results of a mild solution for a fractional nonlocal functional semilinear differential inclusion involving Caputo derivative in Banach spaces. We consider the case when the values of the orient field are convex a... see more

We introduce a new type of functions called almost strongly µ_? -continuous functions which unifies some weak forms of almost strongly ? -continuous functions and investigate their properties.

In this paper we show that, if R is a ring and s an endomorphism of R, then the skew Hurwitz series ring T = (HR, s ) is an n-clean ring if and only if R is an n-clean ring. Moreover, if R is an integral domain and a torsion-free Z-module, then T = (HR, s... see more

Saurabh Porwal, Manoj kumar Singh

In the present paper, we introduce a general integral operator defined by Hadamard product and study mapping properties on some subclasses of analytic univalent functions.  Relevant connections of the results presented here with various known results... see more

We propose a new weak formulation for the plane problem of thermoelastic theory in multiply-connected domains. This permits to avoid the difficulties connected with the Cesaro-Volterra boundary conditions in the related elliptic boundary-value problem. In... see more

In this paper, we investigate several properties of the harmonic class defined by the modified Dziok-Sirvastava operator, obtain distortion theorem, extreme points, convolution condition, convex combinations and integral operator for this class. Some of o... see more

In the present article, we obtain some applications of first order differential subordination, superordination and sandwich results for higher-order derivatives of p-valent functions involving a generalized differential operator. Some of our results impro... see more

In this paper, we improve and further generalize some Ostrowski-Grüss type inequalities for the fractional integrals by using new Montogomery identities.

In this paper, the Riemann-Liouville fractional operator is used to generate new classes of integral inequalities using a family of n positive functions, (n ? N*). For our results, some interesting classical inequalities can be deduced as some special cas... see more

In this paper, we introduce new classes VM(ß ) and VN(ß ) of analytic functions with varying arguments in the open unit disc U = {z ? C : |z| <1}. Some properties such as coefficient estimates, extreme points, distortion theorems for functions f (z) be... see more

In this paper, we investigate differential subordination and superordination properties of a new class of meromorphic analytic functions in the punctured unit disc.We derive some sandwich theorems.

In this paper non-trivial non-linear binary systematic AMDS codes are classified in terms of their  weight distributions, employing only elementary techniques. In  particular, we show that their length and minimum distance completely determine&n... see more

In our present investigation we propose to study and develop the I-function of two variables analogous to the I-function of one variable introduced  and studied by one of the  authors [25]. The conditions for convergence, series representation, ... see more
