Abstract

We consider the Emden‐Fowler equation x” = ‐q(t)|x|x, ε > 0, in the interval [a,b]. The coefficient q(t) is a positive valued continuous function. The Nehari characteristic number An associated with the Emden‐Fowler equation coincides with a minimal value of the functional [] over all solutions of the boundary value problem x” = ‐q(t)|x|x, x(a) = x(b) = 0, x(t) has exactly (n ‐ 1) zeros in (ab).


The respective solution is called the Nehari solution. We construct an example which shows that the Nehari extremal problem may have more than one solution.
