Now, zero is stable, because if x 1 < 1 then x n → 0, but one isn't stable, because if x 1 is greater than 1 then repeated squaring will take x n to infinity, and if x 1 is a bit smaller than 1 then x n converges to zero.

After DeMarr, many researchers studied this subject (see [2–6] and others). On the other hand, in 1975, Baillon [7] proved a mean convergence theorem known as the first nonlinear ergodic theorem in a Hilbert space.
