DESCRIPTION:Sparse operators are positive dyadic operators that have very 
 nice boundedness properties. The L^p bounds and weighted L^p bounds with s
 harp constant are easy to obtain for these operators. In the recent years\
 , it has been proven that singular integrals (cancellative operators) can 
 be pointwise controlled by sparse operators. This has made the sharp weigh
 ted theory of singular integrals quite straightforward. The current effort
 s focus in understanding the use of sparse operators to bound rougher oper
 ators\, such a oscillatory integrals. Following this direction\, our goal 
 in this talk is to describe the control of Bochner-Riesz operators by spar
 se operators.<br><br><br><br><br>
