Universal Polar Dual Pairs in E8 and Leech Lattice
Analysis
Key Takeaways
- •Identifies universal polar dual pairs of spherical codes within E8 and Leech lattice.
- •Provides new insights into the structure of these lattices and their relationship to optimal sphere packings.
- •Introduces a novel approach using lattice properties to find these pairs.
- •Identifies a new universally optimal code in projective space RP^21.
- •Generalizes the Delsarte-Goethals-Seidel definition of derived codes.
“The paper identifies universal polar dual pairs of spherical codes C and D such that for a large class of potential functions h the minima of the discrete h-potential of C on the sphere occur at the points of D and vice versa.”
