Abstract

In this paper, we are concerning with the existence of the solution \( \mathfrak{V} \in L_1([0,\tau],L_2(\Omega))\) of the singular stochastic fractional-order integral equation with delay \(\varrho(.) \), \[ \mathfrak{V}(t) = B(t) t^{\alpha - 1} + \lambda ~ \mathfrak{I}^{\beta} \mathfrak{G}(t,\mathfrak{V}(\varrho (t))), ~~~t\in (0,\tau], \] where \(B(t)\) is a given second order mean square stochastic process, \( \lambda \) is a parameter, \(\varrho (t) \leq t\), and \(\mathfrak{G}(t,\mathfrak{V}) \) is a measurable function in \(t \in (0,\tau]\) and satisfies Lipschitz condition on the second argument. The Hyers-Ulam and generalized Hyers-Ulam-Rassias stability will be proved. Moreover, the continuous dependence of the solution on the process \(B(t)\) and \(\lambda\) will be studied. As applications, some nonlocal, weighted and nonlocal-weighted integral problems of stochastic fractional-order differential equations will be studied.
