The isometric C is related o a moment sequence and such a is studied by the Nevanlinna counting function of hen μ is the normalized Lebesgue measure on the unit circle.Department of Mathematics, Hokkaido University2006engdepartmental bulletin paperVoRhttps://doi.org/10.14943/83952http://hdl.handle.net/2115/6961010.14943/83952Hokkaido University Preprint Series in Mathematics802113https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/69610/1/pre802.pdfapplication/pdf140.24 KB2006
