DESCRIPTION:Let H(u) be the Hilbert transform along the parabola (t\; ut2)
  where u 2 R. For a set U of positive numbers consider the maximal functio
 n HUf = supfH(u)f : u 2 Ug. We obtain (essentially) optimal results for th
 e<br>Lp operator norm of HU when 2 &lt\; p &lt\; 1. The results are proved
  for families of Hilbert transforms along more general non- at homogeneous
  curves. Joint work with Shaoming Guo\, Joris Roos and Po-Lam Yung.<br><br
