A simple homological characterization of string algebras of finite representation type
Mariano Suárez-Álvarez
We prove that among the finite dimensional algebras of finite representation type those that are string algebras are precisely the ones that have the property that the middle term…
Hochschild cohomology of algebras of differential operators tangent to a central arrangement of lines
Francisco Kordon, Mariano Suárez-Álvarez
Given a central arrangement of lines in a -dimensional vector space over a field of characteristic zero, we study the algebra of diffe…
The algebra of differential operators tangent to a hyperplane arrangement
Mariano Suárez-Álvarez
We prove using an extension of Saito's criterion that the algebra of differential operators tangent to a free hyperplane arrangement is generated by the derivations of the arrangem…
Cyclic extensions are radical
Mariano Suárez-Álvarez
We show that finite Galois extensions with cyclic Galois group are radical.
Applications of the change-of-rings spectral sequence to the computation of Hochschild cohomology
Mariano Suárez-Alvarez
We consider the change-of-rings spectral sequence as it applies to Hochschild cohomology, obtaining a description of the differentials on the first page which relates it to the mul…
