The DNS has the following entry for phys-maths.edu.lv
descr: International Institute of Mathematical Physics
changed: email@example.com 20031201
person: BOGDANOFF IGOR
That address now hosts a web-site for the Mathematical Center of Riemannian Cosmology, which mysteriously seems devoted to the work of the Bogdanovs. The newsgroup fr.sci.physique has all sorts of threads devoted to the Bogdanovs. In one posting by the brothers, where they give their e-mail address as “firstname.lastname@example.org”, they helpfully explain that the University of Riga set up the site for them and that’s why it is in the Lithuanian DNS.
One problem: Riga is in Latvia, not Lithuania.
I take this kind of personally because, besides being an American citizen, I also have a Latvian passport (the Latvian version of my name is “Voits”). My father was born in Riga, and he and his parents became exiles at the time of the Soviet occupation starting during World War II. I’ve visited Riga several times (including a visit to the university), first soon after independence on a trip with my father while he was still alive. Riga is a beautiful city, with the downtown not much changed since before the war. In recent years the old city and much of the downtown have been elegantly renovated, and Riga is now once again a large, vibrant city with great restaurants, hotels, shops, etc. And now it has an International Institute of Mathematical Physics.
