Advances in the Theory of Nonlinear Analysis and its Applications

In this paper, we give some sufficient conditions for the existence of periodic solutions for some autonomous nonlinear ordinary differential equations of order n. The proposed method is based on the use of Brouwer's degree and especially the homotopy invariant of the topological degree.

The present paper introduces the novel subfamilies of regular and bi-univalent functions Σ. The prominent group of Fibonacci polynomial ˜Vn(x, y) is utilized with subordination between regular functions in order to shape these subfamilies. In addition we derive coefficients inequalities for functions belonging to these subfamilies. Various results are exposed as separate cases of the current conclusions.

In the current work, we study the temporal dynamics of hepatitis B keeping in view the various routs of transmission and infectious periods. We develop the epidemic model to study its qualitative analysis, while keeping in view the asymptomatic and symptomatic infections periods. We then discuss the well-possedness of the proposed epidemic problem. Particularly, we show the bounded-ness and positivity as well as existence of solution to the proposed epidemic problem. We also calculate the basic reproductive number and discuss the local and global dynamical properties of the considered model. For the local stability, we use the linear stability approach, while for global stability the well known LaSalle's principle are used. Finally, all the theoretical parts have been supported with the help of graphical representation.&nbsp

This article investigates the nonlocal inverse initial boundary-value problem in a rectangular domain, hyperbolic second order inverseproblem. The main objective is to find the unidentified coefficient and offer a solution to the problem. The hyperbolic second-order, nonlinear equation is solved using finite difference method (FDM). However, the inverse problem was successfully solved by the MATLAB subroutine lsqnonlin from the optimization toolbox after being reformulated as a nonlinear regularized least-square op-timization problem with a simple bound on the unknown quantity. Given that the studied problem is often ill-posed and that even a minor error in the input data can have a large impact on the output. Tikhonov's regularization technique is used to generate stable andaccurate results

In this research, a comparison was made between two methods for estimating a semiparametric regression model with the presence of an autocorrelation problem, based on a semiparametric partial linear regression model, which contains a parametric component and a nonparametric component. The two components were estimated using two methods, the first methods is semi parametric generalized least squares estimators(SGLSE) , the second methods is least squares estimators method(LSEM) .Simulation study show the first method is beast than the second method by using mean squares of errors (MSE).

A novel probability model with bounded support is introduced. The formulation of this new probability model is based on inverting the Slashed Pareto distribution. This new distribution has the merit of being very simple and not involving any complex mathematical function in its construction. Some interesting properties like moments, skewness and kurtosis, unimodality, L-Moments, L-skewness and L-kurtosis would be explored in detail. Various Survival properties including survival function, hazard rate function and mean residual life(MRL) like have been given. For estimating the parameters contained in the new model, methods like Method of Moments (MOM) and Maximum Likelihood Estimation (MLE) have been used.

The system of ordinary differential equations that arises in the theory of genetic networks is studied. Attracting sets of a special kind is the focus of the study. These attractors appear as combinations of attractors of lower dimensions,&#x0D; which are stable limit cycles. The properties of attractors are studied. Visualizations and examples are provided.

In this manuscript, we define a new class of control&#x0D; functions classified as ascendant functions. Consequently, we furnish&#x0D; a fuzzy coupled fixed point result, that is different from one available&#x0D; in the literature, using the notion of simulation function; in follow, we&#x0D; validate the result through a non-trivial example. As an inference, we&#x0D; use the result to analyze the existence of a solution for a non-linear&#x0D; system of fuzzy initial value problem involving generalized Hukuhara&#x0D; derivative.

In this paper, the Lomov's regularization method is generalized to a singularly perturbed integro-differential equation with a fractional derivative and with a rapidly oscillating inhomogeneity. The main goal of the work is to reveal the influence of a rapidly changing kernel on the structure of the asymptotics of the problem solution and to study additional boundary functions that are generated by rapidly oscillating inhomogeneities.

Convergence theorems required more assumptions on parameters than fixed point theorems. In this paper we generalize the concept of acute point and we introduce some convergence theorems that holds under the same assumptions on parameters as fixed point theorems.
