abstract = {<p style="text-align: justify;">Two implicit finite difference schemes combined with the Alikhanov&#39;s $L$2-1$σ$-formula are applied to one- and two-dimensional time fractional reaction-diffusion equations with variable coefficients and time drift term. The unconditional stability and $L$2-convergence of the methods are established. It is shown that the convergence order
of the methods is equal to 2 both in time and space. Numerical experiments confirm
the theoretical results. Moreover, since the arising linear systems can be ill-conditioned,
three preconditioned iterative methods are employed.</p>},
