Project description:
Kihara and Pauly recently uncovered an intricate connection between computability theory and topology (“Point degree spectra of represented spaces”, Forum of Mathematics Sigma 2022). They associate a degree structure (called degree spectrum) to a topological space which reflects many of its topological characteristics. For example, the real numbers are associated with the Turing degrees. This connection already has been used to obtain new results in topology using computability-theoretic methods and vice versa, including solving a long-open question by Jayne on the number of sigma-homeomorphism types of Polish spaces. This project is about further exploring this connection.
Concrete research objectives include calculating the degree spectra of more topological spaces exhibiting unusual properties, and to identify topological properties linked to classes of degrees such as the uniformly intro-enumerable ones. A big open question in this area is whether every almost-total enumeration degree is graph-cototal.
Background knowledge in some of pointset topology, computability theory, dimension theory or logic would be helpful.
