    • Certain estimates of oscillatory integrals and extrapolation 

      Al-Qassem, Hussain (2010 , Article)
      In this paper we study the boundedness properties of certain oscillatory integrals with polynomial phase. We obtain sharp estimates for these oscillatory integrals. By the virtue of these estimates and extrapolation we ...

    • A Note on Parabolic Maximal Operators along Surfaces of Revolution via Extrapolation 

      Ali, Mohammed; Al-Qassem, Hussain ( MDPI , 2022 , Article)
      Under weak conditions on the kernels, we obtain sharp Lp bounds for rough parabolic maximal integral operators over surfaces of revolution. By virtue of these bounds along with Yano’s extrapolation argument, we confirm the ...

    • On certain rough integral operators and extrapolation 

      Al-Qassem, Hussain; Cheng, Leslie; Pan, Yibiao ( Victoria university , 2009 , Article)
      In this paper, we obtain sharp Lp estimates of two classes of maximal operators related to rough singular integrals and Marcinkiewicz integrals. These estimates will be used to obtain similar estimates for the related ...
