WebFIXED POINTS OF NONEXPANDING MAPS BY BENJAMIN HALPERN Communicated by F. Browder, July 12, 1967 Introduction. This paper is concerned with nonexpanding … WebA fixed-point theorem for multivalued -nonexpansive mappings in Hadamard spaces is proved. The strong convergence theorems of Browder’s and Halpern’s iterations are also established. Our results generalize and improve the results of Tiammee et al.

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.
