Query: Domain Decomposition Methods for Space Fractional Partial Differential
  Equations   In this paper, a two-level additive Schwarz preconditioner is proposed for
solving the algebraic systems resulting from the finite element approximations
of space fractional partial differential equations (SFPDEs). It is shown that
the condition number of the preconditioned system is bounded by C(1+H/\delta),
where H is the maximum diameter of subdomains and \delta is the overlap size
among the subdomains. Numerical results are given to support our theoretical
findings.
