Property (X+) for second-order nonlinear differential equations of generalized Euler type

A Aghajani, V Roomi - Acta Mathematica Scientia, 2013 - Elsevier
In this paper the generalized nonlinear Euler differential equation t 2 k (tu′) u ″+ t (f (u)+ k
(tu′)) u′+ g (u)= 0 is considered. Here the functions f (u), g (u) and k (u) satisfy …
