Title: Phase unwinding, or invariant subspace decompositions of Hardy spaces,
Abstract: We consider orthogonal decompositions of invariant subspaces of Hardy spaces,
these relate to the Blaschke based phase unwinding decompositions. We prove
convergence in Lp. In particular we build an explicit multiscale wavelet basis.
We also obtain an explicit unwindinig decomposition for the singular inner
function, exp 2i\pi/x.
