Spectra and Definability in Combinatorial Sets of Reals

Explore recent findings on spectra and definability in this 55-minute colloquium presented by Vera Fischer from the University of Vienna. Delve into the study of combinatorial sets of reals, focusing on their possible sizes and their association with cardinal characteristics of the continuum. Examine the projective complexity of witnesses for different cardinalities. Gain insights into advanced mathematical concepts as part of the University of Chicago Department of Mathematics colloquia series, which features "Spectra and Definability" as its central theme.
