We present an iterative solution concept based on a hierarchical separation of the fractures and the surrounding rock matrix. Upper estimates for the convergence rates are independent of the width of the fractures and of the jumps of the coefficients. Inexact solution of the local subproblems is also considered. The theoretical results are illustrated by numerical experiments.<\/p>","DOI":"10.1090\/s0025-5718-05-01792-8","type":"journal-article","created":{"date-parts":[[2005,11,16]],"date-time":"2005-11-16T10:22:35Z","timestamp":1132136555000},"page":"73-90","source":"Crossref","is-referenced-by-count":0,"title":["Hierarchical decomposition of domains with fractures"],"prefix":"10.1090","volume":"75","author":[{"given":"Susanna","family":"Gebauer","sequence":"first","affiliation":[]},{"given":"Ralf","family":"Kornhuber","sequence":"additional","affiliation":[]},{"given":"Harry","family":"Yserentant","sequence":"additional","affiliation":[]}],"member":"14","published-online":{"date-parts":[[2005,10,3]]},"reference":[{"issue":"5","key":"1","doi-asserted-by":"publisher","first-page":"1993","DOI":"10.1137\/S0036142900375414","article-title":"Multigrid methods for anisotropic edge refinement","volume":"40","author":"Apel, Thomas","year":"2002","journal-title":"SIAM J.
