Bangle functions are the generic basis for cluster algebras from punctured surfaces with boundary
Christof Geiß, Daniel Labardini-Fragoso, Jon Wilson
We prove that for any possibly-punctured surface with non-empty boundary , and any tagged triangulation of in the sense of Fomi…
Laminations of punctured surfaces as -regular irreducible components
Christof Geiß, Daniel Labardini-Fragoso, Jon Wilson
Let be a surface with marked points on the boundary, and punctures $\mathbb{P}\subsetΣ\setminu…
On homomorphisms and generically -regular components for skewed-gentle algebras
Christof Geiß
Let be an algebraically closed field with , and a skewed-gentle -algebra. In this case, Crawley-Boevey's description of the indecomposable…
A geometric construction of for affine Kac-Moody algebras of type
Alberto Castillo Gómez, Christof Geiss
Inspired by the work of Geiss, Leclerc and Schröer [Represent. Theory 20, (2016)] we realize the enveloping algebra of the positive part of an affine Kac-Moody Lie algebra of Dynki…
Semicontinuous maps on module varieties
Christof Geiß, Daniel Labardini-Fragoso, Jan Schröer
We study semicontinuous maps on varieties of modules over finite-dimensional algebras. We prove that truncated Euler maps are upper or lower semicontinuous. This implies that -v…
