  • Zerf, Mohammed; Besultan, Hadje; BENNAMA, Benaouda; BEBOUCHA, Wahib (Journal of Physical Education and Sport ® (JPES), 2017-09-30)
    Background. Many East European countries released the weakness of the traditional method and tried to develop methods of identification which could be underpinned by scientific theory and evidence. Aims. The present study ...
  • Zerf, Mohammed; Besultan, Hadje; BENNAMA, Benaouda; BEBOUCHA, WAHIB (2017)

  • Dahmani, Zoubir; Benzidane, A (Malaya Journal of Matematik, 2013)
    In the present paper, we use the fractional q-calculus to generate some new integral inequalities for some monotonic functions. Other fractional q -integral results, using convex functions, are also presented.
  • 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 ...
  • Messirdi, Bekkai; Djellouli, Ghouti (African Journal Of Mathematical Physics, 2007)
    In this paper we present a new reduction scheme that we can applied to the study of Fredholm operators. We mainly show in a simple and original manner the stability results for Fredholm operators. We also get a fundamental ...

  • 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, Sanaa; Messirdi, Bekkai; Messirdi, Miloud (OaM, Oper. Matrices, 2014-03-01)
    The purpose of this paper is to introduce, by means of the extensions of almost closed operators, the notion of almost closable linear operator acting in a Hilbert or Banach space. This class of operators is strictly ...

    In this paper, using the Riemann-Liouville fractional integral operator, we establish new results that generalize some theorems of the work: [A note on some new fractional results involving convex functions. Acta Math. ...
  • Dahmani, Zoubir (Annals of Functional Analysis, 2010)
    In this paper, we use the the Riemann–Liouville fractional inte- gral to develop some new results related to the Hermite–Hadamard inequality. Other integral inequalities related to the Minkowsky inequality are also ...
