Moreover, for any Noetherian local subring of the ring of formal power series, we clarify the relationship between this theorem and the problem of the com-mutation of two operations for ideals: the operation of replacing an ideal by its completion and the operation of replacing an ideal by one of its elimination ideals. %G English %2 https://hal.science/hal-01235349v2/document %2 https://hal.science/hal-01235349v2/file/nested_linear-11-nov.pdf %L hal-01235349 %U https://hal.science/hal-01235349 %~ CNRS %~ UNIV-AMU %~ EC-MARSEILLE %~ INSMI %~ I2M %~ I2M-2014- %~ ANR
