Galois codes for arithmetic and geometry via the power of valuation theory
Also appears in collection : Ordered algebraic structures and related topics / Structures algébriques ordonnées et leurs interactions
We give a survey on recent advances in Grothendiek's program of anabelian geometry to characterize arithmetic and geometric objects in Galois theoretic terms. Valuation theory plays a key role in these developments, thus confirming its well deserved place in mainstream mathematics. The talk notes are available in the PDF file at the bottom of the page.
