    In [1], the automorphism group of a binary linear code is computed by identifying it with one of its optimal generator matrices. This identification is effective for the computation of the automorphism group of a binary linear code. As application, we show in this work th...

    In this paper, we determine when two Cayley graphs over the cyclic group Zpq2 are to be isomorphic, for p 6= q prime numbers. and we determine the all types of automorphism groups of these graphs.

    We focus our attention in this article on some recent results regarding Hardy-Hilbert’s inequalities. We derive an equivalent form using katugampola Fractional Calculus and introduce new analogs to some Hardy-Hilbert’s type inequality. Several special cases are also giv...

    In this paper, we establish the concept of non-self Hardy-Rogers contractions on Banach spaces involving a graph. We also prove some fixed point theorems for such mappings. The results of this paper extend and generalize various known results in the literature.

    In this study, controllability of a class of fractional-order dynamical system with time-varying delays is considered. First, a representation of the solution is given using Laplace transform and Mittageleffler function. Then necessary and sufficient conditions for the ...

    In this paper we consider the nonlinear boundary value problem governed by a stationary perturbed Stokes system with mixed boundary conditions ( Dirichlet-Fourier- maximal monotone graph), in a smooth domain. The existence and regularity of the weak solution to this pro...

    In this paper, we obtain all the symmetric semi-classical linear functionals of class four taking into account the irreducible expression of the corresponding Pearson equation. We focus our attention on their integral representations. Thus, some linear functionals very ...

    In this paper we establish Hyers-Ulam-Rassias stability and Hyers-Ulam Criteria for second order non-linear ordinary differential equations of Lane-Emden type; moreover two examples of such equations are considered

    In this work , we investigate the Aboodh transformation method to solve first order constant coefficients complex equations. This method provides an effective and efficient way of solving a wide range of linear operator equations.

    In this paper, we studied the subgroup in β-α-topological group and several basic theorems are introduced. From normal subgroups, the study naturally follows to quotient groups, which are decomposition spaces topologically. The quotient group space of β-α-topological gr...
