Let X be an algebraic variety, reduced and equidimensional, over the base field k of characteristic zero. Let us consider a sequence of transformations $$ {X_0} = X\xleftarrow{{{\sigma _1}}}{X_1}\xleftarrow{{{\sigma _2}}}{X_2} \leftarrow \cdots $$ where \( {\sigma _i}:{X_i} \to {X_{i - 1}} \) for each \( i \geqslant 1 \) is (1) birational,
