| Abstract: | We prove an estimate for the spherical average operator in  if  . This leads to a lower bound for the Hausdorff dimension of unions of certain collections of spheres and to a Strichartz-type estimate for solutions of the wave equation. |
| Keywords: | Spherical averages Hausdorff dimension Strichartz estimate |
