  • Messirdi, Bekkai; Ould-Ali, Mohand (International Journal of Algebra, 2010)
    Let C(H) be the set of all linear closed operators densely defined on a Hilbert space H. This paper is devoted to the study of the equivalent statements for which an operator A belongs to C(H) has a closed range.
  • Messirdi, B; Ould-Ali, Mohand (Applied Mathematical Sciences, 2010)
    In this paper, we etablish some spectral properties for a general class of multiplication type-operators containing n involutions on the Hilbert space L2 (X,μ) . We construct the resolvent and we investigate the spectrum ...
