Invertibility of some singular integral operators and a lifting theorem
Let P_{+} be an analytic projection and let P_{-} be a co analytic projection.Let L^{2}(W) be the usual weighted Lebesgue space on the unit circle.For some weight W. P_{+} is not continuous in the norm of L^{2}(W) .We shall define the Hilbert space L^{2}((W)) such that for any weight W, …
