Singular positone and semipositone boundary value problems of second order delay differential equations
Jiang, Daqing; Xu, Xiaojie; O’Regan, Donal; Agarwal, Ravi P. (Institute of Mathematics, Czech Academy of Sciences, 2005-06-01)In this paper we present some new existence results for singular positone and semipositone boundary value problems of second order delay differential equations. Throughout our nonlinearity may be singular in its dependent ... -
Solvability of singular dirichlet boundary-value problems with given maximal values for positive solutions
Agarwal, Ravi P.; O’Regan, Donal; Staněk, Svatoslav (Cambridge University Press (CUP), 2005-02-01)The singular boundary-value problem (g(x'(t)))' = muf (t, x(t), x'(t)), x(0) = x(T) = 0 and max {x(t) : 0 less than or equal to t less than or equal to T} = A is considered. Here p is the parameter and the negative function ... -
