2274. Akash Hossain Extension bases in Henselian valued fields E-mail: Submission date: 4 October 2022 Abstract: We give several sufficient conditions for parameter sets in a Henselian valued field of residue characteristic zero to be an extension base. This enables us in particular to show that forking coincides with dividing in (the ^{eq} expansions of) some classical valued fields of residue characteristic zero, like the ultraproducts of the p-adic fields, or the field of Laurent series over ℂ. The strategy is to look for easy sufficient conditions for some unary types to be non-forking, and then use a standard induction argument.
