 We consider the problem of $L^p$ bounds for the cone multiplier operators 
  
 and prove the sharp $L^3$ bounds for the cone multiplier in $\\mathbb R^3$ 
  
 and the associated square function which is known as Mockenhaupt\'s square 
  
 function. The results are obtained by an adaptation of recent 
  
 Bourgain-Guth’s argument for restriction estimates which relies on the 
  
 multilinear restriction theorem due to Bennett-Carbery-Tao. This talk is 
  
 based on a joint work with Ana Vargas.
