We start the discussion with the straightforward approach based on interpolating and extrapolating the slow–fast coupling variables; the multirate Euler scheme, used as a base example, falls into this class. Next we discuss higher order multirate schemes that generalize classical singlerate linear multistep, Runge-Kutta, and extrapolation methods.application/pdfenIn CopyrightArticleabs/2505.20062Sandu, Adrian [0000-0002-5380-0103]
