  • Must there be numbers we cannot describe or define? Definability in mathematics and the Math Tea argument, Norwich, February 2019

    I shall speak for the Pure Mathematics Research Seminar at the University of East Anglia in Norwich on Monday, 25 February, 2019. Abstract. An old argument, heard perhaps at a good math tea, proceeds: “there must be some real numbers …

  • The axiom of well-ordered replacement is equivalent to full replacement over Zermelo + foundation

    In recent work, Alfredo Roque Freire and I have realized that the axiom of well-ordered replacement is equivalent to the full replacement axiom, over the Zermelo set theory with foundation. The well-ordered replacement axiom is the scheme asserting that if …

  1. Dear Joel David Hamkins,

    I would like to buy your new book “a mathematicians year in japan”. Unfortunately Amazon will not let me buy, most likely because I’m not in the U.S. Is there any way to get a print copy instead of a kindle version? Barring that is there perhaps another way to obtain a copy? Thanks in advance!

    Lee

    • Dear Lee,

      I’m very sorry, but the book is not available in paper format. It currently exists only in electronic format, on Kindle. Kindle format books can be read on almost any device (phone, computer, tablet) with the free Kindle application.

      regards,

      JDH
