Maximal almost rigid modules over gentle algebras
Emily Barnard, Raquel Coelho Simoes, Emily Gunawan +1
We study maximal almost rigid modules over a gentle algebra . We prove that the number of indecomposable direct summands of every maximal almost rigid -module is equal to the…
A geometric model for the module category of a string algebra
Karin Baur, Raquel Coelho Simoes
In this paper, we give a geometric construction of string algebras and of their module categories. Our approach uses dissections of punctured Riemann surfaces with extra data at ma…
Simple-minded systems and reduction for negative Calabi-Yau triangulated categories
Raquel Coelho Simoes, David Pauksztello
We develop the basic properties of -simple-minded systems in -Calabi-Yau triangulated categories for . The main result is a reduction technique for negative Cala…
A geometric model for the module category of a gentle algebra
Karin Baur, Raquel Coelho Simoes
In this article, gentle algebras are realised as tiling algebras, which are associated to partial triangulations of unpunctured surfaces with marked points on the boundary. This no…
Endomorphism algebras for a class of negative Calabi-Yau categories
Raquel Coelho Simoes, Mark James Parsons
We consider an orbit category of the bounded derived category of a path algebra of type A_n which can be viewed as a -(m+1)-cluster category, for m >= 1. In particular, we give a c…
Mutations of simple-minded systems in Calabi-Yau categories generated by a spherical object
Raquel Coelho Simoes
In this article, we give a definition and a classification of 'higher' simple-minded systems in triangulated categories generated by spherical objects with negative Calabi-Yau dime…
Torsion pairs in a triangulated category generated by a spherical object
Raquel Coelho Simoes, David Pauksztello
We extend Ng's characterisation of torsion pairs in the 2-Calabi-Yau triangulated category generated by a 2-spherical object to the characterisation of torsion pairs in the w-Calab…
Hom-configurations in triangulated categories generated by spherical objects
Raquel Coelho Simoes
Hom- and Riedtmann configurations were studied in the context of stable module categories of selfinjective algebras and a certain orbit category C of the bounded derived category o…
Maximal rigid objects as noncrossing bipartite graphs
Raquel Coelho Simoes
Let Q be a Dynkin quiver of type A. The bounded derived category of the path algebra of Q has an autoequivalence given by the composition of the Auslander-Reiten translate and the…
Hom-configurations and noncrossing partitions
Raquel Coelho Simoes
Let Q be a Dynkin quiver. The bounded derived category of the path algebra of Q has an autoequivalence given by the composition of the Auslander-Reiten translate and the square of…
