We reached out to our source after TechCrunch reported AdMob's CEO Omar

Hamoui isn't the first to go, and he won't be the last.

发帖数: 8565 | 25 差的这一点在“出个题”中补齐了。
现在我记录一下这个证明：证明Z[sqrt(-5)] is integrally closed.
1. the integral closure of Z[sqrt(-5)] in Q[sqrt(-5)]=Q(sqrt(-5)) is equal
to the integral closure of Z in Q(sqrt(-5)).
2. The integral closure of Z in Q(sqrt(-5)) is Z[sqrt(-5)].
Therefore, the integral closure of Z[sqrt(-5)] in Q(sqrt(-5)) is itself, and
thus it's integrally closed.
1比较容易，因为any element alpha integral over R=Z[sqrt(-5)] has a monic
polynomial r(x) in R[x] such that r(alpha)=0. 把r(x)的系数按照整数和带sqrt(-

-R=>-e=>e=>R=>-R
其中-R=>-e是实轴上的路线, -e=>e表示一个半径为e的小半圆(上半平面), 绕过奇点;
e=>R是实数轴上的线; R=>-R是半径为R的上半平面的圆.
这个回路所围区域留数为零, 所以:
Integrate[Exp[iz]/z, 逆时针(正向)回路]=2 Pi i*(留数)=0
但是上面的回路积分可以分解为:
Integrate[Exp[ix]/x,{x,-R,-e}]
+Integrate[Exp[ix]/x,{x,e,R}]
+Integrate[Exp[iz]/z,{半径为e的顺时针(负向)的小圆弧}]
+Integrate[Exp[iz]/z,{半径为R的逆时针(正向)大圆弧}]
R->Infinity, 根据所谓Jordan引理,
Integrate[Exp[iz]/z,{半径为R的逆时针(正向)大圆弧}]=0;
e->0, 则
Integrate[Exp[ix]/x,{x,-R,-e}]+Integrate[Exp[ix]/x,{x, |
