In his research, Henrik encounters numerous problems and open questions. This list contains some of those questions. It is compiled with the hope that some Internet surfers will be in possession of (partial) answers to some of the questions and be kind enough to establish contact with me using one of the ways described on the main page, www.henrikkragh.dk.

 

  • Any and all biographical information concerning one Mr. Louis Olivier, who published about a dozen papers in the first three volumes of Crelle’s Journal für die reine und angewandte Mathematik, 1826-28.
  • Information on the original publishing of Robert Storm Petersen’s Flue: “Livet er svært, men matematik er sværere”. It was included in the collection 107 Fluer, published 1950, but the drawing is likely to have been published in Berlingske Tidende before that.
  • Information on the fate of the Weierstrass prize instituted by the King of Sweden at the initiative of Gösta Mittag-Leffler to be handed out at the International Congress of Mathematicians in Stockholm in 1916. I am well aware of the announcement of the prize, but as the ICM never happened in 1916, it was apparently not awarded.
  • Table of contents of the third issue of the European Mathematical Society Newsletter. Thanks to the generous help of Åsvald Lima, I have now had access to the first 16 newsletters, except for this third one.
