I heard that Professor Suren Arakelov got mental disorder and ceased research. However, a brief search on the Russian wikipedia page showed he was placed in a psychiatric hospital because of political dissent.
Since in Soviet Union days a healthy person can get into psychiatric hospital because of "sluggish schizophrenia", it is unclear to me whether he was really sick. Perhaps he was tortured and that is why he stopped research? Is he still alive? Does he still give lectures in Moscow?
The whole Arakelov theory obviously owe its foundation to Arakelov's ground-breaking work in 1970s. The invention of Faltings height is stemed from Arakelov theory. I am wondering what is the current situation of Prof. Arakelov (no email, no physical address, only some dubious reports on wikipedia). The whole situation sounds like John Nash, except Arakelov have not recovered.
I ask at here because I honestly do not know who else to ask (I do not know anyone else graduated from Gubkin Russian State University of Oil and Gas in my university).
I received an email forwarded from Prof. Beilinson, written by Prof. Bogomolov, which clarified the matter completely. The alleged event did not happen, even though Prof. Arakelov was warned by the government for his actions. Instead Prof. Arakelov was sick due to private personal reasons. As a result I am voting the post to close.
Thanks for everyone's help in this matter.
