    Singular boundary value problems for superlinear second order ordinary and delay differential equations 

    Agarwal, Ravi P.; O'Regan, Donal (Elsevier BV, 1996-09-01)

    Boundary value problems singular in the solution variable with nonlinear boundary data 

    O'Regan, Donal (Cambridge University Press (CUP), 1996-10-01)
    Existence results are established for the equation y '' +f(t, y) = 0, 0 < t < 1. Here f may be singular in y and f is allowed to change sign. Our boundary data include y(0) = y'(1) + ky(1) = 0, k > -1 and y(0) = ...

    Positive solutions to superlinear singular boundary value problems

    Coincidence points for perturbations of linear fredholm maps of index zero 

    Agarwal, Ravi P.; O'Regan, Donal (European Mathematical Publishing House, 1999-01-01)
    Coincidence points for single and set valued maps are discussed in this paper. We show if F is essential and F congruent to G then G has a coincidence point.

    Boundary value problems of nonsingular type on the semi-infinite interval 

    Agarwal, Ravi P.; O'Regan, Donal (Mathematical Institute, Tohoku University, 1999-01-01)
    Existence of a positive solution is established for second order boundary value problems on the semi-infinite interval.

    O'Regan, Donal (American Mathematical Society (AMS), 1996-02-01)
    The Schauder Tychonoff theorem in a locally convex topological space is used to establish existence results for Volterra-Hammmerstein and Hammerstein integral equations in a reflexive Banach space.
