May 15, 2015 at 19:47 comment added José Hdz. Stgo. @knsam: I would really appreciate it if you did that for me! You can send the scanned document to this email: [email protected] With the aid of it and the Zentralblatt review of which Mr. Brunault has made me aware, I hope to have a clearer view of Ljunggren's demonstration of the result in question.
May 15, 2015 at 13:45 comment added François Brunault According to the Zentralblatt review of Ljunggren's article, the method is to reduce to a (Pell-)Fermat equation. zbmath.org/?q=an:0028.00901

May 15, 2015 at 8:17 comment added knsam I have access to the Collected Works in question and I am willing to scan the paper for you; you must however figure out the Norwegian part... ;-)
May 15, 2015 at 7:36 comment added José Hdz. Stgo. Methinks it would have to be an international interlibrary loan, if such a thing is possible...
May 15, 2015 at 7:33 comment added The Masked Avenger Too bad. I found it at a public library in the U.S. Maybe interlibrary loan?
May 15, 2015 at 7:31 comment added José Hdz. Stgo. That book is out of my reach, too.
May 15, 2015 at 7:29 comment added The Masked Avenger Try Ribenboim's book on the Catalan conjecture, if you can get a hold of that.
