On Riedtmann's Lie algebra of the gentle one-cycle algebra $Λ(n-1,1,1)$
Published 18 Apr 2022 in math.RT | (2204.08141v2)
Abstract: An extended version of Riedtmann's Lie algebra of the gentle one-cycle algebra $\Lambda(n-1,1,1)$ is computed and is shown to admit a Cartan decomposition by the positive roots of the root system of type $\mathbf{BC}_n$.
