A Hopf Algebra from Preprojective Modules

Pak-Hin Li

Let $Q$ be a finite type quiver i.e. ADE Dynkin quiver. Denote by $Λ$ its preprojective algebra. It is known that there are finitely many indecomposable $Λ$ -modules if and only if…

Extensions and their Minimizations on the Sierpinski Gasket

Pak Hin Li, Nicholas Ryder, Robert S. Strichartz +1

We study the extension problem on the Sierpinski Gasket ( $S G$ ). In the first part we consider minimizing the functional $E_{λ} (f) = E (f, f) + λ \int f^{2} d μ$ with p…
