DESCRIPTION:Title: <a href="https://researchseminars.org/talk/paw/52/">Pha
 se space projections</a>\nby Olli Saari (Universität Bonn) as part of Pro
 bability and Analysis Webinar\n\n\nAbstract\nA partition into tiles of the
  area covered by a convex tree in the Walsh phase plane gives an orthonorm
 al basis for a subspace of L2. There exists a related projection operator\
 , which has been an important tool for dyadic models of the bilinear Hilbe
 rt transform. Extending such an approach to the Fourier model is strictly 
 speaking not possible\, but satisfactory substitutes can be constructed. T
 his approach was pursued by Muscalu\, Tao and Thiele (2002) for proving un
 iform bounds for multilinear singular integrals with modulation symmetry i
 n dimension one. I discuss a multidimensional variant of the problem. This
  is based on joint work with Marco Fraccaroli and Christoph Thiele.\n
