　　In this talk,an additive overlapping Schwarz method for isogeometric collocation discretizations is introduced and studied.The resulting preconditioner,accelerated by GMRES,is shown to be scalable with respect to the number of subdomains and very robust with respect to the isogeometric discretization parameters such as the mesh size and polynomial degree,as well as with respect to the presence of discontinuous elliptic coefficients and domain deformations.
