F-stable secondary representations and deformation of F-injectivity

Alessandro De Stefani, Linquan Ma

We prove that deformation of F-injectivity holds for local rings $(R, m)$ that admit secondary representations of $H_{m}^{i} (R)$ which are stable under the natur…

Lim Ulrich sequences and Lech's conjecture

Linquan Ma

The long standing Lech's conjecture in commutative algebra states that for a flat local extension $(R, m) \to (S, n)$ of Noetherian local rings, we have an inequ…

Koszul and local cohomology, and a question of Dutta

Linquan Ma, Anurag K. Singh, Uli Walther

For a local ring $(A, m)$ of dimension $n$ , we study the natural map from the Koszul cohomology module $H^{n} (m; A)$ to the local cohomology module $H^n_\mathfra…
