Regular Talk:
Omega Degree Spectra

Edit abstract data

Speaker: Alexandra Soskova
Slot: Tue, 12:00-12:20, Room 24 (col. 3)


We present a notion of a degree spectrum of a structure with respect to countably many sets, based on the notion of omega enumeration reducibility. We prove that some properties of the degree spectrum such as the minimal pair theorem and the existence of quasi-minimal degree are true for the omega degree spectrum.
