Solvability of an infinite system of nonlinear integral equations of Volterra-Hammerstein type

open access: yesAdvances in Nonlinear Analysis, 2019
The purpose of the paper is to study the solvability of an infinite system of integral equations of Volterra-Hammerstein type on an unbounded interval. We show that such a system of integral equations has at least one solution in the space of functions ...

A comparison of pituitary function in primary and secondary empty sella: preliminary data

open access: yes, 2018
Background Empty sella (ES), the herniation of the subarachnoid space within sella associated with a variable flattening of the pituitary gland, is classified as primary (PES) or secondary (SES) on the basis of etiological factors.

On the existence of solutions of infinite systems of Volterra-Hammerstein-Stieltjes integral equations

open access: yesAdvances in Nonlinear Analysis
In this article, we deal with the solvability of an infinite system of Volterra-Hammerstein-Stieltjes integral equations in the space of continuous and bounded functions defined on R+{{\mathbb{R}}}_{+} with values in the sequence space l1{l}_{1}.

Liouville type theorems involving fractional order systems

open access: yesAdvanced Nonlinear Studies
In this paper, let α be any real number between 0 and 2, we study the following semi-linear elliptic system involving the fractional Laplacian: (−Δ)α/2u(x)=f(u(x),v(x)),x∈Rn,(−Δ)α/2v(x)=g(u(x),v(x)),x∈Rn. $\begin{cases}{\left(-{\Delta}\right)}^{\alpha /2}

Classification of positive solutions for a weighted integral system on the half-space

open access: yesOpen Mathematics
In this article, we study the following weighted integral system: u(x)=∫R+n+1yn+1βf(u(y),v(y))∣x−y∣λdy,x∈R+n+1,v(x)=∫R+n+1yn+1βg(u(y),v(y))∣x−y∣λdy,x∈R+n+1.\left\{\begin{array}{l}u\left(x)=\mathop{\displaystyle \int }\limits_{{{\mathbb{R}}}_{+}^{n+1 ...
