In particular, we give a Littlewood-type theorem to show that the approach region introduced by Kor\'anyi and Taylor (1983) is best possible.Department of Mathematics, Hokkaido University2006engdepartmental bulletin paperVoRhttps://doi.org/10.14943/83960http://hdl.handle.net/2115/6961810.14943/83960Hokkaido University Preprint Series in Mathematics81018https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/69618/1/pre810.pdfapplication/pdf108.67 KB2006
