This approach is suited for the time integration of multiscale ordinary and partial differential equations and provides highly accurate discretizations. We analyze the linear stability properties of the multirate explicit and linearly implicit extrapolated methods. Numerical results with multiscale ODEs illustrate the theoretical findings.application/pdfenIn CopyrightNumerical analysisTechnical reportTR-08-12http://eprints.cs.vt.edu/archive/00001036/01/MRExtrap.pdf
