Injective hulls of odd cycles
Ruedi Suter
The injective hulls of odd cycles are described explicitly.
Young's lattice and dihedral symmetries revisited: Möbius strips and metric geometry
Ruedi Suter
A cascade of dihedral symmetries is hidden in Young's lattice of integer partitions. In fact, for each integer N>2 the Hasse graph of the subposet consisting of the partitions with…
Power sums of Coxeter exponents
John M. Burns, Ruedi Suter
Consider an irreducible finite Coxeter system. We show that for any nonnegative integer n the sum of the nth powers of the Coxeter exponents can be written uniformly as a polynomia…
Quantum affine Cartan matrices, Poincare series of binary polyhedral groups, and reflection representations
Ruedi Suter
We first review some invariant theoretic results about the finite subgroups of SU(2) in a quick algebraic way by using the McKay correspondence and quantum affine Cartan matrices.…
Abelian ideals in a Borel subalgebra of a complex simple Lie algebra
Ruedi Suter
Let g be a complex simple Lie algebra and b a fixed Borel subalgebra of g. We shall describe the abelian ideals of b in a uniform way, that is, independent of the classification of…
Zero Energy States for SU(N): A Simple Exercise in Group Theory ?
M. Bordemann, J. Hoppe, R. Suter
We show that the requirement of invariance for a ``asymptotically free'' SU(3)-Cartan subalgebra wave-function does {\em not} give a unique candidate for a SU(3…
