2575. Masato Fujita Michael's selection theorem in general d-minimal structures E-mail: Submission date: 22 February 2024 Abstract: Thamrongthanyalak demonstrated a definable version of Michael's selection theorem in d-minimal expansions of the real field. We generalize this result to the case in which the structures are d-minimal expansions of ordered fields ℱ=(F,<,+,‧,0,1,…). We also show that we can choose a definable continuous selection f of a lower semi-continuous map T:E → F so that f(x) is contained in the interior of T(x) when the interior is not empty.
