Two inertial CQ-algorithms for generalized split inverse problem of infinite family of demimetric mappings
Two inertial CQ-algorithms for generalized split inverse problem of infinite family of demimetric mappings
en
en
In this paper, two new inertial CQ-algorithms with strong convergence results are constructed to approximate the solution of the generalized split common fixed point problem: given as a task of finding a point that belongs to the intersection of an infinite family of fixed point sets of demimetric mappings such that its image under an infinite number of linear transformations belongs to the intersection of another infinite family of fixed point sets of demimetric mappings in the image space. The algorithms are established based on the CQ-projection method with inertial effect and step-size selection technique so that the implementation of the proposed algorithms does not need any prior information about the operator norms. The proposed methods improve, complement, and generalize many of the important results in the literature.

In this paper, the Gould-Hopper based fully degenerate type2 poly-Stirling
polynomials of the first kind with a \(q\) parameter are considered and some
of their diverse identities and properties are investigated. Then, the
Gould-Hopper based fully degenerate type2 poly-Bernoulli polynomials with a
\(q\) parameter are introduced and some of their properties are analyzed and
derived. Furthermore, several formulas and relations covering implicit
summation formulas, recurrence relations and symmetric property are attained.

Applications of statistical Riemann and Lebesgue integrability of sequence of functions
Applications of statistical Riemann and Lebesgue integrability of sequence of functions
en
en
In the present work, we propose to investigate statistical Riemann integrability, statistical Riemann summability, statistical Lebesgue integrability and statistical Lebesgue summability by means of deferred Nörlund and deferred Riesz mean. We discuss some fundamental theorems connecting these concepts with examples. As an application to our newly formed sequences, we introduce Korovkin-type approximation theorems with relevant example for positive linear operators by using Meyer-König and Zeller operators to exhibit the effectiveness of our findings.

We introduce and study deferred Nörlund statistical convergence in probability, mean of order \(r\), distribution and study the interrelation among them. Based upon the proposed method to illustrate the findings, we present new Korovkin-type theorems for the sequence of random variables via deferred Nörlund statistically convergence and present compelling examples to demonstrate the effectiveness of the results.

On the analytic and approximate solutions for the fractional nonlinear Schrödinger equations
On the analytic and approximate solutions for the fractional nonlinear Schrödinger equations
en
en
In this work, we are devoted to the following fractional nonlinear Schrödinger equation with the initial conditions in the Caputo sense for \(1 < \alpha \leq 2\):
\begin{equation}\label{J1}
\begin{cases}
\displaystyle i \frac{ _c \partial^{\alpha}}{\partial \theta^{\alpha}} W(\theta, \sigma) + \beta_1 \frac{ \partial^{2}}{\partial \sigma^{2}} W(\theta, \sigma) \\
\hspace{0.5in} + \gamma (\theta, \sigma) W(\theta, \sigma) + \beta_2 |W(\theta, \sigma)|^2 W (\theta, \sigma) + \beta_3 W^2 (\theta, \sigma) = 0,\\
W(0, \sigma) = \phi_1(\sigma), \quad W_\theta'(0, \sigma) = \phi_2(\sigma),
\end{cases}
\end{equation}
where \(\theta > 0, \sigma \in \mathbb{R}\), \(\gamma(\theta, \sigma)\) is a continuous function and \(\beta_1, \beta_2, \beta_3\) are constants. Our analysis for deriving analytic and approximate solutions to the Schrödinger equation relies on the Adomian decomposition method and fractional calculus. Several illustrative examples are presented to demonstrate the solution constructions. Finally, the variant and symmetric system of the fractional nonlinear Schrödinger equations are studied.

Auto-oscillation of a generalized Gause type model with a convex contraint
Auto-oscillation of a generalized Gause type model with a convex contraint
en
en
In this paper, we study the generalized Gause model in which the functional and numerical responses of the predators need not be monotonic functions and the intrinsic mortality rate of the predators is a variable function. As a result, we have established sufficient conditions for the existence, uniqueness and global stability of limit cycles confined in a closed convex nonempty set, by relying on a recent Lobanova and Sadovskii theorem. Moreover, we prove sufficient conditions for the existence of Hopf bifurcation. Eventually using scilab, we illustrate the validity of the results with numerical simulations.
