 Abstract：

We consider the H^s-L^q maximal estimates associated to the wave operator  

Rogers Villaroya proved H^s-L^q estimates for the maximal operator up to the eritical Sobolev expouents . However, the endpoint case estimates for the critical exponent have remained open so far.We obtain the endpoint  bounded on the maximal operator . We also prove that several different forms of the maximal estimates considered by Rogers-Villarroya are basically equivalent to each other. This is a joint work with Chuhee Cho and Sanghyuk Lee.
