Minimal Euclidean representations of graphs
Aidan Roy
A simple graph G is said to be representable in a real vector space of dimension m if there is an embedding of the vertex set in the vector space such that the Euclidean distance b…

Bounds for codes and designs in complex subspaces
Aidan Roy
We introduce the concepts of complex Grassmannian codes and designs. Let G(m,n) denote the set of m-dimensional subspaces of C^n: then a code is a finite subset of G(m,n) in which…
