  • On a General Feshbach Method1 
    Messirdi, Bekkai; Benaicha, Slimane; Djaa, Mustapha; Rahmani, Abdelkader (Publié dans International Journal of Mathematical Analysis, Volume1, 2007)
    We present a general reduction Feshbach method that can be applied in particular to the spectral study of operators including the hamiltonian of the Born-Oppenheimer approximation and also to Fredholm operators. This ...
  • 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).
