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.

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

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2021
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 uniqueness for these equations. Finally, we present some examples to illustrate our results.

Oscillations of Volterra integral equations with delay [PDF]

open access: bronzeTohoku Mathematical Journal, 1993
The oscillatory behavior of the solutions of a Volterra type equation with delay is investigated. Sufficient conditions on the kernel are given which guarantee that the oscillatory character of the forcing term is inherited by the solutions.

Singular Volterra integral equations

open access: yesApplied Mathematics Letters, 2000
AbstractExistence results are presented for the singular Volterra integral equation y(t) = h(t) + ∫0t k(t, s) f(s, y(s)) ds, for t ∈ [0,T]. Here f may be singular at y = 0. As a consequence new results are presented for the nth order singular initial value problem.

On a perturbed Volterra integral equation

open access: yesJournal of Mathematical Analysis and Applications, 1970
AbstractFor the Volterra integral equation x(t) = f(t) − ∝0t a(t, s)(x(s) + g[s, x(s)]) ds, if the resolvent kernel of a(t, s) is sufficiently well-behaved, and if ¦g(t, x)¦ → 0 as t → ∞ in some sense, then ¦x(t) − y(t)¦ → 0 as t → ∞, where y(t) is the solution of y(t) = f(t) − ∝0t a(t, s) y(s) ds.

On a Volterra Stieltjes integral equation [PDF]

open access: hybridInternational Journal of Stochastic Analysis, 1990
The paper deals with a study of linear Volterra integral equations involving Lebesgue‐Stieltjes integrals in two independent variables. The authors prove an existence theorem using the Banach fixed‐point principle. An explicit example is also considered.

Generalised Dirichelt-to-Neumann map in time dependent domains [PDF]

open access: yes, 2012
We study the heat, linear Schrodinger and linear KdV equations in the domain l(t) < x < ∞, 0 < t < T, with prescribed initial and boundary conditions and with l(t) a given differentiable function.

Solvability of a Volterra–Stieltjes integral equation in the class of functions having limits at infinity

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2017
The paper is devoted to the study of the solvability of a nonlinear Volterra–Stieltjes integral equation in the class of real functions defined, bounded and continuous on the real half-axis $\mathbb{R}_+$ and having finite limits at infinity.
