  • -boundedness and-compactness of a class of Fourier integral operators. 
    Messirdi, Bekkai; Senoussaoui, Abderrahmane (Electronic Journal of Differential Equations (EJDE)[electronic only], 2006)
    In this paper, we study the L2− boundedness and L2− compactness of a class of Fourier integral operators. These operators are bounded (respect ively compact) if the weight of the amplitude is bounded (respectively tends to0).
  • An Example of Unbounded Fourier Integral Operator on L2 with Symbol in 
    Messirdi, Bekkai; Aıboudi, Mohamed; Senoussaoui, Abderrahmane (2007)
    In this paper, we give an example of Fourier integral operator with a symbol belongs to 0<ρ<1 S0 ρ,1 that cannot be extended as a bounded operator on L2 (Rn) .
  • On the L2-boundedness and L2-compactness of a class of Fourier integral operators 
    Messirdi, Bekkai; Senoussaoui, Abderrahmane (Electronic Journal of Differential Equations, 2006-01-01)
    In this paper, we study the L 2-boundedness and L2-compactness of a class of Fourier integral operators. These operators are bounded (respectively compact) if the weight of the amplitude is bounded (respectively tends to 0).
