Triacontagonal proofs of the Bell-Kochen-Specker theorem
P. K. Aravind, Justin Y. J. Burton, Guillermo Núñez Ponasso +1
Coxeter pointed out that a number of polytopes can be projected orthogonally into two dimensions in such a way that their vertices lie on a number of concentric regular triacontago…
Ehrhart Polynomials of Generic Orthotopes
David Richter
A generic orthotope is an orthogonal polytope whose tangent cones are described by read-once Boolean functions. The purpose of this note is to develop a theory ofEhrhart polynomial…
Splints of classical root systems
David A. Richter
This article introduces a new term "splint" and classifies the splints of the classical root systems. The motivation comes from representation theory of semisimple Lie algebras. In…
Triacontagonal coordinates for the E(8) root system
David A. Richter
This note gives an explicit formula for the elements of the E(8) root system. The formula is triacontagonally symmetric in that one may clearly see an action by the cyclic group wi…
Quantization of cohomology in semi-simple Lie algebras
R. Milson, D. Richter
The space of realizations of a finite-dimensional Lie algebra by first order differential operators is naturally isomorphic to H^1 with coefficients in the module of functions. The…
