In this paper, I study to solve functional inequalities and equations of type Cauchy-Jensen with 3k-variables in a general form. I first introduce the con-cept of the general Cauchy-Jensen equation and next, I use the direct method of proving the solutions of the Jensen-Cauchy functional inequalities relative to the general Cauchy-Jensen equations and then I show that their solutions are mappings that are additive mappings calculated and finally apply the de-rivative setup on fuzzy algebra also ...

In this article, I use the direct method to study two general functional inequalities with multivariables. First, I prove that the g(λ)-function inequalities (1) and (2) are additive in (α 1;α 2)-homogeneous F-spaces. After that, I continue to prove that the g(λ)-function inequality (1) and (2) are quadratic in the (α 1;α 2)-homogeneous F-space. That is the main result in this paper.

In this paper, we investigate the existence of normalized solutions to the coupling of the nonlinear Schrödinger-Maxwell equations. In the mass-subcritical case, we by weak lower semmicontinuity of norm prove that the equations satisfying normalization condition exist a normalized ground state solution.

In this article, I study the establishment of the quadratic-additive η-function inequality with 3k-variables on the homogeneous complex Banach space and prove the quadratic-additive η-function equation related to the additive and quadratic η-functional inequalities in (α 1,α 2)-homogeneous Banach complex space.

In this paper, I work on expanding the Quadratic Φ( μ1, μ2)-function inequalities by relying on the general quadratic functional equation with 2k-variables on the fuzzy Banach space. That’s the main result of this.

In this paper, we study the existence of normalized solutions to the Klein-Gordon-Maxwell systems. In the mass-subcritical case, we prove that the systems satisfying normalization conditions have a normalized ground state solution.

In this paper we provide a computational approach to a minimization problem for the value function associated with an affine optimal control problem subject to terminal-constraint with quadratic cost plus a potential, for a fixed final time and initial point. We study the global minimization problem of the value function over the attainable set and the regularity properties of the value function at a global minimizer point. On the other hand, in the global minimization of the value function, by ...

In this paper, I study to establish general Cauchy-Jensen μj-function inequalities by relying on general Cauchy-Jensen equations with 3k-variables on complex Banach spaces. First, I investigated the Cauchy-Jensen μj-function inequalities in complex Banach spaces and then I establish Isomorphisms between Unital Banach Algebras. These are the main results of this paper.

This paper presents the analysis of a two-stage negative binomial group testing estimator of the prevalence of a rare trait when imperfect diagnostic tests with known sensitivity and specificity were used. The study utilized the method of Maximum Likelihood Estimation (MLE) to obtain the estimator and the Cramer-Rao lower bound method to compute the Fischer information of the estimator. The properties of the constructed estimator are discussed and the efficiency of the constructed estimator rela...
