Monte Carlo computability
We introduce Monte Carlo computability as a probabilistic concept of computability on infinite
objects and prove that Monte Carlo computable functions are closed under composition. …

Cardinal invariants, non-lowness classes, and Weihrauch reducibility
N Greenberg, R Kuyper, D Turetsky - Computability, 2019 - content.iospress.com
We provide a survey of results using Weihrauch problems to find analogs between set
theory and computability theory. In our treatment, we emphasize the role of morphisms in …
