  • MEZALI, Karim (Numéro spécial du Bulletin du Centre National de Développement des Ressources Biologiques (CNDRB), Ministère de l'aménagement du Territoire et de l'environnement (MATE), Alger, Algérie, 2011-09)
    Cette étude s'intéresse à cinq espèces d'holothuries aspidochirotes : Holothuria (Holothuria) tubulosa (Gmelin, 1790) : Holothuria (Lessonothuria) poli (Delle Chiaje, 1823) ; Holothuria (Holothuria) stellati (Delle Chiaje, ...
  • Zerf, Mohammed; Besultan, Hadje; BENNAMA, BENAOUDA; BEBOUCHA, WAHIB (www.efsupit.ro, 2017-09)
    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 ...

  • Benchabane, Lahcen (2018)
    Since the beginnings of the 20th century linguists shown huge interest to develop foreign language teaching methods, the common aim of these strategies is to limit and reduce the negative impact of issues that might face ...
  • 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 ...
  • Bensedik, Ahmed; Bouchekif, Mohammed (Electronic Journal of Differential Equations (EJDE)[electronic only], 2002)
    The purpose of this article is to nd positive solutions to the system 􀀀 pu = m(x)@H @ u(u; v) in 􀀀 qv = m(x)@H @ v(u; v) in (1:1) u = v = 0 on@ where is a bounded regular domain of RN; with a smooth ...
  • Bouchekif, Mohammed (Funkcialaj Ekvacioj, 1998)
    In this paper, we consider the existence of positive solutions of the fol-lowing problem: $(¥ ovalbox {¥ tt¥ small REJECT} _ {p}) $$¥ left¥{¥ begin {array}{l}-¥ Delta_ {p} um (x) g (u)-¥¥ u= 0¥ end {array}¥ right. $$¥ ...
  • 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 ...
  • Messirdi, Bekkai; Mortad, Mohammed Hichem (Banach J. Math. Anal, 2008-01-01)
    The purpose of this work is to give different products of closed operators together with their faults and assets.
  • Dahmani, Zoubir; Bounoua, Mohamed Doubbi (2018)
    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 ...
  • Bouchekif, Mohammed; Messirdi, Sofiane (Taiwanese Journal of Mathematics, 2016)
    In this paper we consider a class of nonhomogeneous elliptic equations involving multi-polar Hardy type potentials and a Sobolev critical nonlinearity in an open domain of , . By Ekeland's Variational Principle and the ...
  • Belaidi, Benharrat; El Farissi, Abdallah; Latreuch, Zinelaâbidine (JIPAM, 2009)
    In this paper, we give a complete answer to Problem 1 and a partial answer to Problem 2 posed by F. Qi in [2] and we propose an open problem. Acknowledgements: The authors would like to thank the referees for their helpful ...
  • Belaidi, Benharrat; ElFarissi, Abdallah (Electronic Journal of Qualitative Theory of Differential Equations, 2009)
    In this paper, we investigate the relationship between small functions and differential polynomials gf (z) = d2f 00 + d1f 0 + d0f, where d0 (z), d1 (z), d2 (z) are meromorphic functions that are not all equal to ...
  • Benharrat Belaïdi; Zinelâabidine Latreuch (Arab. J. Math., 2018)
    In this paper, we study the value distribution of zeros of certainnonlinear difference polynomials of entire functions of finite order.
