Approximate inverse preconditioners for linear systems arising from spatial balanced fractional diffusion equations

We consider the preconditioned iterative methods for the linear systems arising from the finite volume discretization of spatial balanced fractional diffusion equations where the fractional differential operators are comprised of both Riemann-Liouville and Caputo fractional derivatives. The coeffici...
