Journal of Applied Mathematics, Volume 2026, Issue 1, 2026.In this paper, we obtained conditions for the uniqueness of solution and a Crank–Nicholson–type algorithm for fractal‐fractional differential equations with a power law kernel in Riemann–Liouville sense. For the uniqueness analysis, Kooi′s conditions are imposed on the problem.
