Weihrauch degrees

Weihrauch degrees are a way to measure and compare the computational difficulty of mathematical problems or functions. Think of them as a hierarchy where problems are grouped based on whether one can be transformed into another using a computable process. If one problem can be uniformly reduced to another, they are considered equivalent at the same degree. This framework helps us understand the relative complexity of problems, especially those involving infinite or non-computable elements, by organizing them into these degrees. Essentially, Weihrauch degrees serve as a tool to classify and analyze the inherent computational content of mathematical tasks.
