F. Skof investigated an interesting asymptotic property of the additive functions (see Theorem 2.34). In fact, she proved that a function f : E₁ → E₂ is additive if and only if ‖f(x + y) − f(x) − f(y)‖ → 0 as ‖x‖ + ‖y‖ → ∞, where E₁ is a normed space and E₂ is a Banach space.
Looking to the east we could see Api and the mountains of west Nepal, shapely snow peaks in the distance, while in the immediate foreground, much lower but still dramatic, were the peaks of Panch Chuli IV and V (III was hidden by the lip of a huge cornice), Telkot and Nagling, all of them unclimbed, all steep and challenging.
