Complex Two-Graphs via Equiangular Tight Frames
Thomas Hoffman, James Solazzo
In `A survey of two-graphs' \cite{Sei}, J.J. Seidel lays out the connections between simple graphs, two-graphs, equiangular lines and strongly regular graph. It is well known that…
Complex Equiangular Tight Frames and Erasures
Thomas Hoffman, James Solazzo
In this paper we demonstrate that there are distinct differences between real and complex equiangular tight frames (ETFs) with regards to erasures. For example, we prove that there…
Numerical Measures for Two-Graphs
David M. Duncan, Thomas R. Hoffman, James P. Solazzo
We study characteristics which might distinguish two-graphs by introducing different numerical measures on the collection of graphs on vertices. Two conjectures are stated, one…
Interpolation and Balls in C^k
Vern I. Paulsen, James P. Solazzo
We compare and classify various types of Banach algebra norms on mathbb{C}^k through geometric properties of their unit balls. This study is motivated by various open problems in i…
