Daniel Chen, Sebastian Ohlig

We explore new connections between complete non-ambiguous trees (CNATs) and permutations. We give a bijection between tree-like tableaux and a specific subset of CNATs. This map is…

On the number of tilting modules over a class of Auslander algebras

Dan Chen, Xiaojin Zhang

Let $Λ$ be a radical square zero algebra of a Dynkin quiver and let $Γ$ be the Auslander algebra of $Λ$ . Then the number of tilting right $Γ$ -modules is $2^{m - 1}$ if $Λ$ is of $A_{…
