چکیده

In this article, we present a novel approach for solving systems of nonlinear fractional Volterra integro-differential equations (NFVI-DEs) by reproducing the Hilbert kernel method (RKM). Kernel methods are powerful tools for addressing both linear and nonlinear problems. The reproducing kernel method stands out for its wide-ranging applications in solving complex scientific challenges. Our method combines the reproducing kernel method with a truncated Taylor series expansion, resulting in a more precise solution. This transformation converts the original NFVI-DEs into a system of nonlinear fractional differential equations (NFDEs). Our numerical results showcase this approach's effectiveness and align with theorems about error analysis.
