[數撚圍爐區] abc conjecture is still a conjecture (3)

我做嗰時都有諗過 都覺得唔squeeze 得 兩個bound 都唔同


但如果用呢條thm個方向諗又幫唔幫到手



btw 用Cauchy好易 好彩巴打你講一講prove

第二條thm基本上淨係用黎quick check divergence

係唔係比漏左condition, a b可以唔同

sequence ge squeeze theorem 一定要a=b

我指個solution好似錯錯地， 應該用cauchy去做

Squeeze thm for sequence要 a, b同value, 唔係嘅話會fail; take a_n = -1, b_n = 1, c_n = (-1)^n

佢個solution用squeeze有問題; 除非佢assume series a_n and b_n converge to the same limit.
