    • $A_1$ theory of weights for rough homogeneous singular integrals and commutators 

      Pérez, C.Autoridad BCAM; Rivera-Ríos, I.P.; Roncal, L.Autoridad BCAM (2019)
      Quantitative $A_1-A_\infty$ estimates for rough homogeneous singular integrals $T_{\Omega}$ and commutators of $\BMO$ symbols and $T_{\Omega}$ are obtained. In particular the following estimates are proved: \[ \|T_\Omega ...
    • Bilinear Calderón--Zygmund theory on product spaces 

      Li, K.; Martikainen, H.; Vuorinen, E. (2019-10)
      We develop a wide general theory of bilinear bi-parameter singular integrals $T$. This includes general Calder\'on--Zygmund type principles in the bilinear bi-parameter setting: easier bounds, like estimates in the Banach ...
    • New bounds for bilinear Calderón-Zygmund operators and applications 

      Damián, W.; Hormozi, M.; Li, K. (2016-11-25)
      In this work we extend Lacey’s domination theorem to prove the pointwise control of bilinear Calderón–Zygmund operators with Dini–continuous kernel by sparse operators. The precise bounds are carefully tracked following ...
    • Vector-valued operators, optimal weighted estimates and the $C_p$ condition 

      Cejas, M.E.; Li, K.; Pérez, C.Autoridad BCAM; Rivera-Ríos, I.P. (2018-09)
      In this paper some new results concerning the $C_p$ classes introduced by Muckenhoupt and later extended by Sawyer, are provided. In particular we extend the result to the full range expected $p>0$, to the weak norm, to ...
