La théorie géométrique des diviseurs élémentaires d’après M. Krull. (Russian. French summary) Zbl 0015.00104
Trav. Univ. Odessa, Math. 1, 89-108 (1935).
The author follows the ideas of Krull’s papers on abelian groups [Math. Z. 23, 161–196 (1925; JFM 51.0116.03); Sitzungsber. Heidelb. Akad. Wiss. 1926, No. 1, 32 S. (1926; JFM 52.0111.02)] and develops, in a geometrical language, the theory of elementary divisors for an arbitrary number field. With the aid of some simple geometrical concepts he establishes the fundamental theorems for a decomposition of vector space into cyclic subspaces, which enable him to obtain easily the canonical forms for a matrix, and some other well-known results of matrix theory.
