This week's seminar will be in the MALL (in the Physics Research Deck) and will be on Tuesday 9th December at 1.30pm. We will meet before the seminar at about 1.10pm in the common room just outside the MALL for tea, coffee, and (of course) biscuits.
Week 11, Tuesday 9th December
Will Anscombe Existential theories of equicharacteristic henselian valued fields
We discuss some recent work (joint with Arno Fehm) about a `weak transfer principle' for equicharacteristic henselian valued fields. More precisely, we transfer the truth of existential sentences (in a suitable language for valued fields) between these fields, subject to some constraints on the residue fields.
