Higher spin representations of maximal compact subalgebras of simply-laced Kac-Moody-algebras
Robin Lautenbacher, Ralf Köhl
Given the maximal compact subalgebra of a split-real Kac-Moody algebra of type , we study certain finite-dimensional representations of $\mat…
Representations of Quantum Minimal Surface Algebrasvia Kac-Moody-theory
Jens Hoppe, Ralf Köhl, Robin Lautenbacher
We consider epimorphisms from quantum minimal surface algebras onto involutroy subalgebras of split real simply-laced Kac-Moody algebras and provide examples of affine and finite t…
Representations of involutory subalgebras of affine Kac-Moody algebras
Axel Kleinschmidt, Ralf Köhl, Robin Lautenbacher +1
We consider the subalgebras of split real, non-twisted affine Kac-Moody Lie algebras that are fixed by the Chevalley involution. These infinite-dimensional Lie algebras are not of…
Extending generalized spin representations
Robin Lautenbacher, Ralf Köhl
We revisit the construction of higher spin representations by Kleinschmidt and Nicolai for E10, generalize it to arbitrary simply laced types, and provide a coordinate-free approac…
