Integral Planes and Unit-Norm Polytopes
Daniele Corradetti
We introduce and study integral planes associated with crystallographic and non-crystallographic integral systems in real composition algebras. For an integral order $\Order$ in su…

Integral Shell Polytopes of Composition Algebras
Daniele Corradetti
Integral systems in real composition algebras give rise to finite metric configurations whose geometry is linked to both regular polytopes and root-systems. In this work we investi…
