  • Existence and Uniqueness for Volterra equations (VE) with a weak regularity assumption on A, the relative closedness of A are investigaed by means of the Laplace transform theory. Also, (VE) are studied by means of the method of convoluted solution operator families.

  • The stability of a class of Volterra-type difference equations that include a generalized difference operator ∆a is investigated using Krasnoselskii's fixed point theorem and some results are obtained. In addition, some examples are given to illustrate our theoretical results.

  • Let Yp be the multiplication operator Mp plus the Volterra operator Vp induced by p(z), where p is a polynomial. Under a mild condition, we prove that Yp acting on the Dirichlet space 𝔇 is similar to multiplication operator Mp acting on a subspace S(𝔻) of 𝔇. Furthermore, it shows that Tzn (n ≥ 2) has exactly 2n reducing subspaces on 𝔇.

  • In this paper, we examine the existence and bounded- ness of the solutions of discrete Volterra equations $$x(n)=f(n)+\sum_{j=0}^{n}g(n,j,x(j))$$, $n{\geq}0$ and $$x(n)=f(n)+\sum_{j=0}^{n}B(n,j)x(j)$$, $n{\geq}0$.
