Weak Solutions of a Coupled System of Urysohn-Stieltjes Functional (Delayed) Integral Equations

Existence and multiplicity of positive solutions for a coupled system of perturbed nonlinear fractional differential equations

In this paper, we consider a coupled system of nonlinear fractional differential equations (FDEs), such that both equations have a particular perturbed terms. Using emph{Leray-Schauder} fixed point theorem, we investigate the existence and multiplicity of positive solutions for this system.

Convex Solutions of a Nonlinear Integral Equation of Urysohn Type

Existence of solutions of differential and integral equations is subject of numerous investigations see, e.g., the monographs 1–3 or 4 . Moreover, a lot of work in this domain is devoted to the existence of solutions in certain special classes of functions e.g., positive functions or monotone functions . We merely mention here the result obtained by Caballero et al. 5 concerning the existence o...

Existence of infinitely many solutions for coupled system of Schrödinger-Maxwell's equations

existence and approximate $l^{p}$ and continuous solution of nonlinear integral equations of the hammerstein and volterra types

بسیاری از پدیده ها در جهان ما اساساً غیرخطی هستند، و توسط معادلات غیرخطی ‎‏بیان شد‎‎‏ه اند. از آنجا که ظهور کامپیوترهای رقمی با عملکرد بالا، حل مسایل خطی را آسان تر می کند. با این حال، به طور کلی به دست آوردن جوابهای دقیق از مسایل غیرخطی دشوار است. روش عددی، به طور کلی محاسبه پیچیده مسایل غیرخطی را اداره می کند. با این حال، دادن نقاط به یک منحنی و به دست آوردن منحنی کامل که اغلب پرهزینه و ...

On a perturbed functional integral equation of Urysohn type

Keywords: Functional integral equation Existence Monotonic solutions Urysohn Compact in measure a b s t r a c t We study the existence of monotonic solutions for a perturbed functional integral equation of Urysohn type in the space of Lebesgue integrable functions on an unbounded interval. The technique associated with measures of noncompactness (in both the weak and the strong sense) and the D...
