• The Sparse T1 Theorem 

      Lacey, Michael T.; Mena Arias, Darío Alberto (2017)
      We impose standard T1-type assumptions on a Calderon-Zygmund operator T, and deduce that for bounded compactly supported functions f and g there is a sparse bilinear form B so that |< Tf, g >|; < B(f,g). The proof is short ...
