Qualitative properties of nonlinear Volterra integral equations

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2008
Summary: The contraction mapping principle and Lyapunov's method are used to study qualitative properties of nonlinear Volterra equations of the form \[ x(t) = a(t) -\int^{t}_{0}C(t,s)g(s,x(s))\;ds,\quad t\geq0. \] In particular, the existence of bounded solutions and solutions with various \(L^p\) properties are studied under suitable conditions on ...

An Algorithm for the Solution of Nonlinear Volterra–Fredholm Integral Equations with a Singular Kernel

open access: yesFractal and Fractional, 2023
The nonlinear Volterra–Fredholm integral Equation (NVFIE) with a singular kernel is discussed such that the kernel of position can take the Hilbert kernel form, Carleman function, logarithmic form, or Cauchy kernel. Using the quadrature method, the NVFIE

Oscillation Theorems of Nonlinear Volterra-Stieltjes Integral Equations

open access: yesJournal of Mathematical Analysis and Applications, 1995
The oscillatory behavior of solutions to the nonlinear Volterra-Stieltjes integral equation \[ p(t) \psi (y) y'_+ (t)= c+ \int^t_0 f(y (s)) d\sigma (s) \] is considered. \(y'_+ (t)\) denotes the right derivative of \(y(t)\), \(p(t)> 0\) and \(\sigma (t)\) are right-continuous and of locally bounded variation on \([0, \infty)\), \(\psi: (- \infty ...

On Monotonic and Nonnegative Solutions of a Nonlinear Volterra-Stieltjes Integral Equation

open access: yesJournal of Function Spaces, 2014
We study the existence of monotonic and nonnegative solutions of a nonlinear quadratic Volterra-Stieltjes integral equation in the space of real functions being continuous on a bounded interval. The main tools used in our considerations are the technique

Asymptotically periodic solutions of Volterra integral equations

open access: yesElectronic Journal of Differential Equations, 2016
We study the existence of asymptotically periodic solutions of a nonlinear Volterra integral equation. In the process, we obtain the existence of periodic solutions of an associated nonlinear integral equation with infinite delay.

On the Stability of Numerical Methods for Nonlinear Volterra Integral Equations

open access: yesDiscrete Dynamics in Nature and Society, 2010
Here we investigate the behavior of the analytical and numerical solution of a nonlinear second kind Volterra integral equation where the linear part of the kernel has a constant sign and we provide conditions for the boundedness or decay of solutions ...

An Analytical and Approximate Solution for Nonlinear Volterra Partial Integro-Differential Equations with a Weakly Singular Kernel Using the Fractional Differential Transform Method

open access: yesInternational Journal of Differential Equations, 2018
An analytical-approximate method is proposed for a type of nonlinear Volterra partial integro-differential equations with a weakly singular kernel. This method is based on the fractional differential transform method (FDTM).
