The resolution of the bracket powers of the maximal ideal in a diagonal hypersurface ring

Andrew R. Kustin, Hamid Rahmati, Adela Vraciu

Let $k$ be a field. For each pair of positive integers $(n, N)$ , we resolve $Q = R / (x^{N}, y^{N}, z^{N})$ as a module over the ring $R = k [x, y, z] / (x^{n} + y^{n} + z^{n})$ . Write $N$ in the form $N = an + r$ …

Contracting Endomorphisms and Gorenstein Modules

Hamid Rahmati

We characterize Gorenstein modules over those local rings that admit a finite contracting endomorphism.

Free resolutions of parameter ideals over some rings with finite local cohomology

Hamid Rahmati

Let $R$ be a noetherian local ring. We consider the following quastion: Does there exist an integer $n$ such that all idelas generated by a system of parameters contained in the $n…
