Comment (by chapoton):
Found some typos:
* homoenize
* coordiante (several times)
* coordiantes (several times)
* generatred
* dehomgenize
For arxiv references, you may use the syntax {{{:arxiv:`1210.6246`}}}
You should write
{{{
.. TODO::
}}}
One suggestion of shorter (equivalent) code for the hash function of
points over finite fields
{{{
p = self.codomain().base_ring().order()
N = self.codomain().ambient_space().dimension_relative()
return sum(hash(self[i])*p**i for i in range(N+1))
}}}
I suggest (but this is optional) to use the Python3 syntax for the raise
statements:
{{{
raise ValueError("can not dehomogenize at 0 coordinate")
}}}
