Chebotarëv and his density theorem
The authors sketch the life of N. G. Chebotarëv (1894-1947), most famous for his density theorem in algebraic number theory. Two-thirds of the paper are devoted to Chebotarëv's mathematics. These include a brief history and explanation of the density theorem and its importance, together with a sketch of a proof of it which does not use class field theory (the historical situation). Also included are two further results of Chebotarëv; one on Vandermonde determinants, which has application to the singularities of gap series, and one dealing with whether a certain class of numbers is constructible. The paper, both mathematically and historically, is very clearly written. There is a picture of Chebotarëv. One small note: while transliteration is always a problem, and the Mathematical Review Journals' standard is an appropriate one to follow, it is nevertheless a little strange to see Alexander Ostrowski (who, though Russian, spent his career in German speaking institutions, chiefly Göttingen and Basel) referred to as Ostrovskii.
