I'm a 2nd year master's student of mathematics, specializing in algebraic topology.

I have Bc.S. degrees in mathematics and physics.

My interests include topology, geometry and mathematical physics, and more specifically abstract homotopy theory and cobordism theory.

@user26857 I may do that once I have had time to work a bit more on it, in light of the comments I recieved here.

comment Power series modulo polynomials
Thank you for the references! So the question can be summarized as: "Is an abelian group always a pure subgroup of its completion wrt. a separated filtration?" right?

comment Power series modulo polynomials
I see. There is a problem with infinite sums, of course. Thank you for pointing it out. Does the failure to be pure exact persist if we replace Z with a (alg. closed?) field? Also, in what way is it nasty?

You can probably post this on Mathoverflow to get a higher chance of an answer.
