abstract:
This paper is devoted to the asymptotic analysis of positive solutions of a
class of second order functional differential equations in the framework of
regular variation. It is shown that precise asymptotic behavior of intermediate
positive solutions of the equations under consideration can be established by
means of Karamata's integration theorem combined with fixed point techniques.
