Three Old Pieces

Kees Doets

Haagkerslaan 14, NL-1185 DJ Amstelveen


This contribution consists of three pieces that are independent of each other. The first one recalls an expedition into Swedish Lapland undertaken by Johan and myself 25 year ago and is mainly picturesque, the second one is a remark to Johan's 1972 Master's Thesis centering around a new equivalent of the Prime Ideal Theorem, and the final one is a short proof of the Boundedness Theorem that is fundamental for the paper of Johan and Jon Barwise on pebble games.
