1. Singular positone and semipositone boundary value problems of second order delay differential equations Creator: Jiang, Daquing, Xu, Xiaojie, O’Regan, Donal, and Agarwal, Ravi P. Format: bez média and svazek Type: model:article and TEXT Subject: existence, positone problem, semipositone problem, and singular delay differential equations Language: English Description: 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 variable. Rights: http://creativecommons.org/publicdomain/mark/1.0/ and policy:public
