WebHence we can choose a closed point $\mathfrak q$ which is contained in the nonempty open \[ V \setminus \{ \mathfrak q \subset B \mid \mathfrak m_ A = \mathfrak q \cap A\} . \] (Nonempty by assumption, open because $\{ \mathfrak m_ A\} $ is a closed subset of $\mathop{\mathrm{Spec}}(A)$.) Then $\mathop{\mathrm{Spec}}(B/\mathfrak q)$ has two ...

In this setting, several results on the density of smooth divisors satisfying certain conditions are needed to construct the rationally equivalent smooth 1-cycle. I will also sketch how Poonen's closed point sieve works to get such density ... indian realtor in san ramon
