Convergence Analysis of Schwarz Waveform Relaxation for Nonlocal Diffusion Problems
Figure 6
Convergence factor based on different parameter : with analyzed at the continuous level (see Lemma 4), analyzed at the discrete level (see Theorem 2), and obtained from numerical optimizations (see Remark 2). (a) (backward Euler); (b) (BDF2, i.e., the two-step backward difference formula).
