    Singular problems modelling phenomena in the theory of pseudoplastic fluids 

    Agarwal, Ravi P.; O'Regan, Donal (Cambridge University Press (CUP), 2003-10-01)
    Existence criteria are presented for nonlinear singular initial and boundary value problems. In particular our theory includes a problem arising in the theory of pseudoplastic fluids.

    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 ...

    Degenerate anisotropic differential operators and applications 

    Agarwal, Ravi; O'Regan, Donal; Shakhmurov, Veli (Springer Nature, 2011-01-01)
    The boundary value problems for degenerate anisotropic differential operator equations with variable coefficients are studied. Several conditions for the separability and Fredholmness in Banach-valued L-p spaces are given. ...

    Singular integral equations and applications to nonlinear conjugate problems 

    Chu, Jifeng; O'Regan, Donal (The Mathematical Society of the Republic of China, 2010-04-01)
    In this paper, we establish the existence of multiple positive solutions for singular integral equations. The proof is based on a general existence principle established using a nonlinear alternative principle of Leray-Schauder ...
