  • Properties of solutions of fourth-order differential equations with boundary conditions 

    Saker, Samir H; Agarwal, Ravi P; O’Regan, Donal (Springer Nature, 2013-01-01)
    In this paper, we establish some sufficient conditions for (2, 2)-disconjugacy and study the distribution of zeros of nontrivial solutions of fourth-order differential equations. The results are extended to cover some ...
  • Some dynamic wirtinger-type inequalities and their applications 

    Agarwal, Ravi; Bohner, Martin; O’Regan, Donal; Saker, Samir (Mathematical Sciences Publishers, 2011-10-08)
    In this paper, we present some new Wirtinger-type inequalities on time scales. As special cases, some new continuous and discrete Wirtinger-type inequalities are given. The obtained inequalities are applied to a certain ...
