Non-even least energy solutions of the Emden-Fowler equation. (English) Zbl 1248.34023
The author considers non-even positive solutions of the Emden-Fowler equation $u''(t)+h(t)u^p=0\;\;\text{in}\;\;(-1,1),\;\;\;\;u(-1)=u(1)=0,$ where $$p>1,\;h\in L^{\infty}(-1,1),\;h(t)$$ is even and $$h(t)\geq 0, \,\not \equiv 0$$. They prove that if the density of the coefficient function $$h$$ is thin in the interior of (-1,1) and thick on the boundary, then a least energy solution is not even.
