The young scientist from New Zealand, Ellen Hammatt, tells fem*MA about her new project: 

“My ESPRIT project, “Hierarchies of Turing Degrees and Higher Recursion Theory”, considers a transfinite hierarchy of Turing degrees based on the relative complexity of mind changes in computable approximations. It explores higher versions of this hierarchy by moving from computation over the natural numbers to computation over admissible ordinals. In this setting, computations have limit stages where infinitely many steps have already taken place, a phenomenon not present in classical computation. The project aims to understand how the choice of ordinal affects the structure of these hierarchies and the behavior of the corresponding degrees.”
