The Hochschild cohomology ring of the numerical semigroup algebras of embedding dimension two
Nghia T. H. Tran, Emil Sköldberg
Let and be two coprime positive integers and an arbitrary field. We determine the ring structure of the Hochschild cohomology of the numerical semigroup algebras $k[s^{…
The minimal resolution of a cointerval edge ideal is multiplicative
Emil Sköldberg
We show that the minimal resolution of the quotient of the polynomial algebra over a field by a cointerval edge ideal can be given the structure of a DG-algebra.
Algebraic Morse theory and homological perturbation theory
Emil Sköldberg
We show that the main result of algebraic Morse theory can be obtained as a consequence of the perturbation lemma of Brown and Gugenheim.
Resolutions of modules with initially linear syzygies
Emil Sköldberg
We introduce the class of modules with initially linear syzygies, which includes ideals with linear quotients, and study their minimal resolutions. Using a contracting homotopy for…
