Transferring algebra structures on complexes

Claudia Miller, Hamidreza Rahmati

We discuss a homological method for transferring algebra structures on complexes along suitably nice homotopy equivalences, including those obtained after an application of the Per…

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…
