Thursday September 19 17:15 room 105 (14-th line V.I., 29)
One of the standard ways to study absolute Galois groups of fields is via embedding problems. These are not solvable in general, but recently a conjecture was made which identified a large class of embedding problems which should always have a solution. In my talk I will introduce embedding problems and talk about the proof of various special cases of this conjecture, including joint work with Tomer Schlank, Endre Szabó and Gereon Quick. If time permits I will also talk about the relationship to the Hopkins-Wickelgren conjecture, and the current status of the latter.
Everyone is welcome!
