# Constructive Analysis in the Agda Proof Assistant

Proof assistant software has recently been used to verify proofs of major theorems, yet even the libraries of some of the most prominent proof assistants lack much of undergraduate mathematics. In particular, the Agda proof assistant has no formalization of the real numbers and their arithmetic. In this thesis, I present my implementation of Errett Bishop's constructive real numbers in Agda, including their arithmetic, ordering, and fundamental results, such as uncountability and Cauchy completeness. We will also survey the basic concepts of constructive analysis and the Agda proof assistant.
