Tóm tắt: To compute the function reg I^n of a graded ideal I is usually very hard. We will present an explicit formula for reg I^n in terms of an initial ideal of the defining ideal of the Rees algebra of I. This formula is inspired by Bayer-Stilman' method for the computation of reg I in terms of Gin(I).
