In this paper, for a measurable function v and a weight function w, the generalized Riesz projection P v is defined by P vf = vP(v -1f). (f ∈ L p(w)). If P0 is the self-adjoint projection from L2 (w) onto H2 (w), then P0 = P α for some outer function α satisfying w = |α| -2 . In this paper, P v on L p (w) is studied. As an application, the invertibility criterion for the generalized Toeplitz operator Tφv and the generalized singular integral operator φPv+Qv, Qv = I - Pv are investigated using the weighted norm inequality. The operator norm inequality for the generalized Hankel operator Hφv is also presented.Departmental Bulletin Paperapplication/pdfhttp://hdl.handle.net/2115/69562info:doi/10.14943/83904https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/69562/1/pre754.pdfHokkaido University Preprint Series in Mathematics7541262005engpublisher
