Exceptional sequences in semidistributive lattices and the poset topology of wide subcategories
Emily Barnard, Eric J. Hanson
Let be a finite-dimensional algebra over a field . We describe how Buan and Marsh's -exceptional sequences can be used to give a "brick labeling" of a certain poset of wi…

The Bernardi formula for non-transitive deformations of the braid arrangement
Ankit Bisain, Eric J. Hanson
Bernardi has given a general formula for the number of regions of a deformation of the braid arrangement as a signed sum over boxed trees. We prove that each set of boxed trees whi…

Resolution quiver and cyclic homology criteria for Nakayama algebras
Eric J. Hanson, Kiyoshi Igusa
If a Nakayama algebra is not cyclic, it has finite global dimension. For a cyclic Nakayama algebra, there are many characterizations of when it has finite global dimension. In [She…
