Loy, RichardDavies, A RAnderssen, Robert S2015-12-080004-9727http://hdl.handle.net/1885/37495The duality proof of sampling localization given by Loy, Newbury, Anderssen and Davies in 2001 contains an oversight, as the classes of functions chosen do not assume the compact support. Here, it is shown how a minor change to the argument there yields a precise conclusion.Keywords: duality; regularization; relaxation spectrum recovery; sampling localization200910.1017/S00049727080010442016-02-24
