This space arises naturally when modeling electromagnetic problems under axial symmetry and performing a dimension reduction via cylindrical coordinates. We prove that if the original three-dimensional domain is convex, then the multigrid V-cycle applied to the inner product in this space converges, provided certain modern smoothers are used. For the convergence analysis, we first prove several intermediate results, e.g., the approximation properties of a commuting projector in weighted norms, and a superconvergence estimate for a dual mixed method in weighted spaces. The uniformity of the multigrid convergence rate with respect to mesh size is then established theoretically and illustrated through numerical experiments.<\/p>","DOI":"10.1090\/s0025-5718-2010-02384-1","type":"journal-article","created":{"date-parts":[[2010,7,6]],"date-time":"2010-07-06T17:17:12Z","timestamp":1278436632000},"page":"2033-2058","source":"Crossref","is-referenced-by-count":11,"title":["Multigrid in a weighted space arising from axisymmetric electromagnetics"],"prefix":"10.1090","volume":"79","author":[{"given":"Dylan","family":"Copeland","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jayadeep","family":"Gopalakrishnan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Minah","family":"Oh","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"14","published-online":{"date-parts":[[2010,5,24]]},"reference":[{"issue":"219","key":"1","doi-asserted-by":"publisher","first-page":"957","DOI":"10.1090\/S0025-5718-97-00826-0","article-title":"Preconditioning in \ud835\udc3b(\ud835\udc51\ud835\udc56\ud835\udc63) and applications","volume":"66","author":"Arnold, Douglas N.","year":"1997","journal-title":"Math.
