Volterra–Stieltjes integral equations and impulsive Volterra–Stieltjes integral equations

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2020
In this paper, we prove existence and uniqueness of solutions of Volterra–Stieltjes integral equations using the Henstock–Kurzweil integral. Also, we prove that these equations encompass impulsive Volterra–Stieltjes integral equations and prove the ...

Existence and global attractivity of periodic solution for impulsive stochastic Volterra-Levin equations [PDF]

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2012
In this paper, we consider a class of impulsive stochastic Volterra-Levin equations. By establishing a new integral inequality, some sufficient conditions for the existence and global attractivity of periodic solution for impulsive stochastic Volterra ...

Admissibility and Nonlinear Volterra Integral Equations [PDF]

open access: bronzeProceedings of the American Mathematical Society, 1970
Nonlinear perturbations of linear Volterra integral equations are studied in an abstract setting which contains and generalizes some earlier results on the same problem. The perturbed problem is first written as a variation of constants equation on a Fréchet space.

On the oscillation of a Volterra integral equation [PDF]

open access: bronzeCzechoslovak Mathematical Journal, 1995
The author studies oscillation criteria for the integral equation \[ X(t)= f(t)- \int^t_0 a(t, s) g(s, X(s)) ds,\quad t\geq 0.\tag{\(*\)} \] Sufficient conditions for all solutions of equation \((*)\) to oscillate as well as growth estimates for the solutions are given.

A Volterra integral equation of the first kind

open access: bronzeJournal of Mathematical Analysis and Applications, 1976
In animal studies of the effect of the deposition of radioactive debris in the lung, use is made of very small spheres (about 10 ..mu..m diameter) of ZrO/sub 2/ impregnated with plutonium, an ..cap alpha..-particle emitter. A quality control problem that arises in the manufacture of these spheres is that of determining the radial density distribution ...

Oscillations of Volterra integral equations with delay [PDF]

open access: bronzeTohoku Mathematical Journal, 1993
Consider the Volterra integral equation with delays \(x(t)=f(t)-\int_ 0^ t K(t,s,x_ s)ds\), \(t\geq 0\), where \(f\in C(\mathbb{R}^ +,\mathbb{R})\), \(K(t,s,\varphi)\) is continuous in \(t\) and \(\varphi\), and maps bounded sets into bounded sets.
