拟合理想与Gorenstein性质

Fitting ideals and the Gorenstein property

Burcu Baran

摘要:

设p是素数,G是有限交换群,使得p^{2}不整除G的阶.本文证明了对群环Z_{p} [G]上的每个有限模M,不等式#MPDMATHABMN # Z_{p} [G]/Fit_{ Z_{p} [G]}(M)成立.这里,Fit_{ Z_{p} [G]}(M)是M的Z_{p} [G]拟合理想。

英文摘要:

Let p be a prime number and G be a finite commutative group such that p^{2} does not divide the order of G. In this note we prove that for every finite module M over the group ring Z_{p}[G], the inequality #M \leq #Z_{p}[G]/Fit_{Z_{p}[G]}(M) holds. Here, Fit_{Z_{p}[G]}(M) is the Z_{p}[G]-Fitting ideal of M.
