2011-05-02

・(Thoughts) I realized that the valuation-theoretic problem left

pending in my comments of 2011-03-03 may be resolved quite easily.

In particular, one may derive the main theorem obtained in Pop-Stix'

work on the p-adic Section Conjecture as a consequence of an entirely

elementary argument in graph theory and commutative algebra (i.e.,

without resorting to the use of difficult arithmetic results such

as Tamagawa's ``resolution of nonsingularities''). Click here for

more details.

・(Thoughts) As I explained in a previous note, one may apply the work

of Pop-Stix on the p-adic Section Conjection to reduce the Profinite

p-adic Section Conjecture to its tempered counterpart (a remark

due to Y. Andre). On the other hand, I recently noticed that this

reduction may also be obtained as a consequence of an entirely

elementary graph-theoretic argument (i.e., without resorting to

the use of difficult arithmetic results such as Tamagawa's

``resolution of nonsingularities''). Click here for more details.

2010-11-02

・(Thoughts) I realized, with regard to the relationship between the

``combinatorial section conjecture'' and the work of Pop-Stix on

the p-adic Section Conjection, that a similar argument holds over

more general fields and for more general sets of primes Σ. This

lead me to modify the argument I gave on 2010-10-29. Click here

for more details.

2010-10-29

・(Thoughts) I recently realized that the work of Pop-Stix on the
