On integral equations of Urysohn–Volterra type

Applied Mathematics and Computation, 2003
The existence of solutions to Urysohn-Volterra integral equations in a locally convex topological Hausdorff space is established using the Schauder-Tychonoff theorem.

A note on fuzzy Volterra integral equations

Fuzzy Sets and Systems, 1996
An existence and uniqueness theorem for a fuzzy Volterra equation is proved. Fuzzy notions and methods are used due to \textit{O. Kaleva} [Fuzzy Sets Syst. 24, 301-317 (1987; Zbl 0646.34019)]. The paper contains some misprints (e.g., the integral symbol in Theorem 2.2. (i) or the power symbols \(G^2\), \(G^n\) in the proof of Theorem 3.2).

Singularly Perturbed Volterra Integral Equations

SIAM Journal on Applied Mathematics, 1987
The authors study the singularly perturbed Volterra integral equation \[ \epsilon u(t)=\int^{t}_{0}K(t-s)F(u(s),s) ds,\quad t\geq 0, \] where \(\epsilon\) is a small parameter, with the objective of developing a methodology that yields the appropriate ''inner'' and ''outer'' integral equations, each of which is defined on the whole domain of interest ...

Volterra Integral Equations

2012
In this chapter, our attention is devoted to the Volterra integral equation of the second kindwhich assumes the form $$\phi (x) = f(x) + \lambda \,{\int \nolimits }_{a}^{x}\,K(x,t)\,\phi (t)\,\mathrm{d}t.$$ (4.1) Volterra integral equations differ from Fredholm integral equations in that the upper limit of integration is the variable x ...

Volterra Integral Equations

2017
This book offers a comprehensive introduction to the theory of linear and nonlinear Volterra integral equations (VIEs), ranging from Volterra's fundamental contributions and the resulting classical theory to more recent developments that include Volterra functional integral equations with various kinds of delays, VIEs with highly oscillatory kernels ...

Integrability of Resolvents of Systems of Volterra Equations

SIAM Journal on Mathematical Analysis, 1981
The integrability of the resolvents of systems of Volterra integral and integrodifferential equations is studied. The matrix kernels in the equations need not be integrable, and some of the conditions used are shown to be both necessary and sufficient.

Volterra Integral Equations

1995
As shown by equations (1.1.1–2), there is a close relationship between ordinary differential equations and Volterra integral equations. First, we discuss the unique solvability. Afterwards, in §2.1.2, we discuss the regularity of the solution.

Integral Volterra Equations

2016
In this chapter, we conducted a thorough examination of the Volterra integral equation of the second kind for an arbitrary real parameter λ, assuming that the free term f (x) is real-valued and continuous on the interval [a, b] and that the kernel K(x, t) is real-valued, continuous, and separable on the square Q(a, b) = {(x, t): [a, b] × [a, b]}.

Volterra Integral Equations

1970
In this chapter we investigate operator equations and inequalities for functions of one real variable. Our particular objective here is nonlinear Volterra integral equations and ordinary differential equations. Unless explicitly stated otherwise, the Lebesgue concept of integral is always presupposed.
