| Summary: | Abstract The current study pursues the specific goal of determining the approximate solution of the linear stochastic fractional Itô-Volterra integral equations which has been caused by fractional Brownian motion under Hurst parameter 0 < H < 1 $0 < H< 1$ , using a numerical approach. The obtained results are based on a stochastic operational matrix of integration on generalized block-pulse basis function. In fact, we transform the equation to a linear system of algebraic equations via a lower triangular coefficients matrix from the equation, and get an approximation solution with accuracy of order O ( h 2 ) $O(h^{2})$ by solving it. Then the error analysis is revealed by some theorems and definitions. Finally, an application exhibits applicability and accuracy of the method numerical. |
