Stević, Stevo
Existence of nontrivial solutions of a rational difference equation. (English)
[J] Appl. Math. Lett. 20, No. 1, 28-31 (2007). ISSN 0893-9659

The author determines the asymptotic behaviour of a special solution of $$x_{n+1}= (x_n+ x_{n-1}+ x_{n-2} x_{n-3})/(x_n x_{n-1}+ x_{n-2}+ x_{n-3})$$ which confirms a conjecture of {\it L. Ladas} [J. Difference Equ. Appl. 4, No. 5, 497--499 (1998; Zbl 0925.39004)] concerning the existence of a solution being not eventually constant.
