Hilfer fractional advectiondiffusion equations with power-law initial condition; a numerical study using variational iteration method
We propose a Hilfer advectiondiffusion equation of order 0 0.7 ? > 0.7 at a given time t t ; but for ? 0.7 ? > 0.7 the required number of terms increases rapidly with the accuracy level and also with the fractional order ? ? .
