Positive solutions for nonlinear singular boundary value problems on the half line
(Hikari Ltd, 2007)We discuss the existence of positive solutions for singular second order boundary value problems x'' = ?f(t, x, x'), ax(0) ? bx'(0) = k ? 0, x'(?) = 0, where f may be singular at x = 0 and x' = 0 and can change sign. ...
