一个Hacker News帖子讨论了liamoc.net上关于域理论的讲义笔记。一位评论者称赞其清晰的表达,但质疑其内容是否超越了1982年的成果,尤其是在Andy Pitts在90年代探索的关于域的推理方面。另一位用户回应说,域理论的研究自90年代后期以来已经大大减缓,许多理论家退休或转行,同时也提到了Andy Pitts最近当选皇家学会会员。另一位用户回忆Liam O'Connor做过关于这个主题的系列讲座。讨论还链接到了用于构建网站的工具“forester”,以及其创建者Jon Sterling构建它的动机。

    The tool used for this site is Jon Sterling's "forester": https://sr.ht/~jonsterling/forester/

    His motivation for building it is described here: https://www.forester-notes.org/tfmt-0001/index.xml



    Thanks for the link. Is there anything new in these notes? They are cleanly presented but look like the greatest hits up to about 1982. Is there anything in there about reasoning about domains? e.g. what Andy Pitts made hay out of in the 1990s.


    Domain theory has reduced to a trickle, with almost no new results since the late 1990s. Most domain theorist have retired, or moved on to other things. Aside, Andy Pitts has been made a fellow of the Royal Society a few days ago!


    I saw the title and thought “I remember Liam O’Connor giving a lecture series on this for TypeSIG” - PL really is tiny…
