Abstract
The main result is the proof of the fact that one can perform a finite number of monoidal transformations with nonsingular centers in such a way that any two nonsingular birationally isomorphic threefolds become isomorphic outside codimension 2, and the subsets at which the varieties are not isomorphic consist of unions of nonsingular rational curves transversally intersecting with each other. Bibliography: 8 titles.
