推 c76068 :我猜猜看 Fn = [f(x+1/n)-f(x)]/(1/n) 是measurable 06/10 19:08
→ c76068 :Fn -> f' everywhere 所以 f' measurable 06/10 19:09
推 rebe212296 :我記得measurable apostal蠻詳細的 06/10 19:55
→ lenbancy :謝謝c大給個方向 06/11 19:28
Show that
if f: R --> R is a differentiable function , then
f' : R --> R is a measurable function .
測度這一塊才剛學 有沒有高手能給個方向
順便問一下這方面有哪本書會講的比較詳細
感激不盡
