Abstract
<p> <div>I will give an outline of ongoing work with Jochen Koenigsmann on recovering valuations from Galois-theoretic data. In particular, I will sketch a proof of how to recover, from an isomorphism G_K(2) \simeq G_k(2) of maximal pro-2 quotients of absolute Galois groups, where k is the field of 2-adic numbers, a valuation with nice properties. The latter group is a natural example of a so-called Demushkin group.</div> <div></div> <div>Everyone welcome!&nbsp;</div> </p>
