Rigid integral representations of quivers over arbitrary commutative rings
William Crawley-Boevey
In earlier work, the author classified rigid representations of a quiver by finitely generated free modules over a principal ideal ring. Here we extend the results to representatio…
Semilinear clannish algebras
Raphael Bennett-Tennenhaus, William Crawley-Boevey
We define a class of associative algebras generalizing 'clannish algebras', as introduced by the second author, but also incorporating semilinear structure, like a skew polynomial…
On deformed preprojective algebras
William Crawley-Boevey, Yuta Kimura
Deformed preprojective algebras are generalizations of the usual preprojective algebras introduced by Crawley-Boevey and Holland, which have applications to Kleinian singularities,…
Combinatorics of faithfully balanced modules
William Crawley-Boevey, Biao Ma, Baptiste Rognerud +1
We study and classify faithfully balanced modules for the algebra of lower triangular by matrices. The theory extends known results about tilting modules, which are classif…
Decomposition of persistence modules
Magnus Bakke Botnan, William Crawley-Boevey
We show that a pointwise finite-dimensional persistence module indexed over a small category decomposes into a direct sum of indecomposables with local endomorphism rings. As an ap…
A new approach to simple modules for preprojective algebras
William Crawley-Boevey, Andrew Hubery
The work of the first author on the moment map for representations of quivers included a classification of the possible dimension vectors of simple modules for deformed preprojecti…
