Abstract Nonlinear Volterra Equations with Positive Kernels
SIAM Journal on Mathematical Analysis, 1986The author studies the existence of solutions of the equation \[ u(t)+\int^{t}_{0}a(t-s)Au(s)ds\ni f(t),\quad t\geq 0 \] in a Hilbert space. Here the operator A is a nonlinear, possibly multivalued, operator from the space into itself and it is assumed to be pseudomonotone and finitely continuous (for example the sum of a monotone operator defined on ...

On Nonlinear Volterra Equations with Nonintegrable Kernels
SIAM Journal on Mathematical Analysis, 1980In this paper, the asymptotic behavior of solutions of the nonlinear real Volterra equation \[x(t) + \int_0^t {g(x(t - s))a(s)ds = f(t),\quad t \geqq 0} \] is studied. Here a and f are given and x is the unknown function. The assumptions on the function f are rather weak, and in most cases it is assumed that $\int _0^\infty a(s)ds = + \infty $.

Fredholm–Volterra integral equation with singular kernel
Applied Mathematics and Computation, 2003The author considers the Fredholm-Volterra integral equation of the second kind \[ \delta\phi(x,t)+\int\limits_{-1}^1 \left| \ln| y-x| -d\right| \phi(y,t)\,dy+\int\limits_0^t F(\tau)\phi(x,\tau) \,d\tau=f(x,t),\tag{1} \] where \(| x| \leq1,\) \( t\in[0,T],\) \(\lambda\in(0,\infty),\) \(\delta\in(0,\infty]\), with a specific right-hand side \(f(x,t ...
