摘要
We answer a question raised by G. Ladas at the ICDEA 2009 conference, by showing that the non-autonomous difference equation x(n+1) = 1/(x(n) + A(n)) with x(n), A(n) > 0 and A(n) -> 0 with the ratios A(n+1)/A(n) bounded can have solutions whose set of accumulation points contain a non-degenerate interval.
