A second-order accurate numerical method with graded meshes is proposed and analyzed.for an evolution equation with a weakly singular kernel. The graded meshes are employed.to compensate for the singular behavior of the exact solution at t = 0. For the time.discretization, the product integration rule is used to approximate the Riemann–Liouville.fractional integral, a generalized Crank–Nicolson time-stepping is considered and shown.that the error is of order k2, where k denotes the maximum time step. A fully discrete.difference scheme is constructed with space discretization by compact difference method..Numerical experiment is carried out to support the theoretical results. The comparison.between the method on uniform grids and graded grids shows the efficiency of our.method.
