Si la serie (con la norma supremo) no es convergente.
Dar un contraejemplo donde

De todos modos ya pude resolver el problema.
En este orden:

1) Demostré que converge en norma y por lo tanto uniformemente.

2) Demuestro que converge.

3) Con los resultados anteriores, uso la definición de límite para demostrar que
.

¿Me podrás dar un contraejemplo de que no se puede hacer el intercambio entre suma y límite cuando no es convergente?

Gracias y saludos. :)
