    Existence and multiplicity of solutions for some three-point nonlinear boundary value problems 

    Xian, Xu; O'Regan, Donal (Springer Nature, 2006-01-01)
    We study the existence and multiplicity of solutions for the three-point nonlinear boundary value problem u '' ( t) +lambda a(t) f (u) = 0, 0 < t < 1; u( 0) = 0 = u(1)-gamma u(eta), where eta is an element of (0,1), ...

    Existence and multiplicity of positive solutions for singular semipositone $p$-laplacian equations 

    Agarwal, Ravi P.; Cao, Daomin; Lü, Haishen; O'Regan, Donal (Canadian Mathematical Society, 2006-06-01)
    Positive solutions are obtained for the boundary value problem [GRAPHICS] Here f(t, u) >= -M, (M is a positive constant) for (t, u) is an element of [0, 1] X (0, infinity). We will show the existence of two positive ...
