Logic Seminar - Athipat Thamrongthanyalak
Title: Michael's selection theorem in d-minimal expansions of the real fieldSpeaker: Athipat Thamrongthanyalak (The Ohio State University)Abstract: In 1956, E. Michael gave a sufficient condition for the existence of continuous selections of set-valued maps. The construction involves an infinitary process. Therefore, this construction may produce a selection with infinite oscillation even when the set-valued map is a polygon (as a set). This gives rise to the question: If a set-valued map is well-behaved in some prescribed sense, can we find a continuous selection that is similarly well-behaved? In this talk, we give a positive answer to this question in d-minimal expansions of the real field.
