Para cualesquiera u, v ∈ Y se tiene f (u) + f (v) = f (u + v) ≤ p(u + v) = p(u − x0 + x0 + v) ≤ p(u − x0 ) + p(x0 + v), esto es, f (u) − p(u − x0 ) ≤ p(x0 + v) − f (v). La arbitrariedad de u y v permite deducir que sup {f (u) − p(u − x0 ) : u ∈ Y } ≤ ´ınf {p(x0 + v) − f (v) : v ∈ Y } . Sea α cualquier número real en la situación sup {f (u) − p(u − x0 ) : u ∈ Y } ≤ α ≤ ´ınf {p(x0 + v) − f (v) : v ∈ Y } . Considérese la aplicación h : Y + Lin({x0 }) → R dada por h(y + λx0 ) = f (y) + λα, ∀y ∈ Y, ∀λ ∈ R.

En su demostración no es necesario el Teorema de Hahn-Banach. Se incluye aquí por el claro paralelismo que tiene con el resultado anterior. 13 Sea M un subespacio cerrado de un espacio normado X y sea π la proyección canónica de X en X/M. La aplicación T : (X/M )∗ → M ◦ dada por T (f ) = f ◦ π es un isomorfismo isométrico. 1. 3. 41 Operadores transpuestos Hasta el momento hemos obtenido una serie de consecuencias, con las que mostramos cómo el teorema de Hahn-Banach es útil para el desarrollo de la teoría de dualidad.

Sea ν una seminorma sobre un espacio vectorial X y sea M = {x ∈ X : ν(x) = 0}. Claramente M es un subespacio de X. La aplicación x+M −→ ν(x), de X/M en R define una norma en X/M. En los siguientes ejemplos mostramos casos particulares de este último hecho. 30 Capítulo 1. Espacios normados. 3 Funciones de variación acotada Decimos que g : [a, b] −→ R es una función de variación acotada en [a, b] si verifica n V (g; [a, b]) = sup{ |g(ti ) − g(ti−1 )|} < ∞, i=1 donde el supremo anterior se toma sobre todas las particiones P = {a = t0 < t1 < ...
