Introduction
摘要
In the first part of the book, we investigate the problem of computable presentability for spaces and algebraic structures. Much of the theory revolves around a few basic definitions of computability that are tested and compared in various natural classes of mathematical structures. In the next few sections we will meet the main players in this book, and also give some of the main motivating themes. We will always bear in mind our central theme of unifying the countable and uncountable.
