I think there is a shorter proof: By assumption
g
is not contained in any of the minimal primes of the support of
M
. Thus not contained in any of the minimal associated primes, Lemma 10.62.6. By Lemma 10.102.7 there are no embedded associated primes. Applying Lemma 10.62.9 we see that
g
is a nonzerodivisor on
M
. Lemm... |

I've noticed a couple of typos in this proof. Halfway through there is a rogue
h
which should be a
g

x \in Z_i
i=1, \ldots, n
", I think

By the way, the version of this statement when

Draw a flag that would generate the same volume no matter if it were rotated about the
x
y
-axis. Is there more than one possible shape of flag that meets this requirement? Does your flag have any special property that ensures these equal volumes of rotation?
What type of symmetry will your flag need to have? |
