Popis:	This paper gives a detailed exposition of the construction of models of tori that are not decomposable over the base field. The presence of a finite number of nonconjugate subgroups in the group GL(n,Z) enables one to classify the tori of given dimension by the Bravais type of their modules of rational characters. A quite complete description of projective Demazure models in low dimensions is given. The rationality of tori with cubic character lattices is proved. Bibliography: 15 titles.
