Group-invariant max filtering
Jameson Cahill, Joseph W. Iverson, Dustin G. Mixon +1
Given a real inner product space and a group of linear isometries, we construct a family of -invariant real-valued functions on that we call max filters. In the case…
A note on tight projective 2-designs
Joseph W. Iverson, Emily J. King, Dustin G. Mixon
We study tight projective 2-designs in three different settings. In the complex setting, Zauner's conjecture predicts the existence of a tight projective 2-design in every dimensio…
Frames over finite fields: Basic theory and equiangular lines in unitary geometry
Gary R. W. Greaves, Joseph W. Iverson, John Jasper +1
We introduce the study of frames and equiangular lines in classical geometries over finite fields. After developing the basic theory, we give several examples and demonstrate finit…
Multiplication-invariant operators and the classification of LCA group frames
Marcin Bownik, Joseph W. Iverson
In this paper we study the properties of multiplication invariant (MI) operators acting on subspaces of the vector-valued space . We characterize such operators…
The Zak transform and representations induced from characters of an abelian subgroup
Joseph W. Iverson
We consider a variant of the Zak transform for a finite group with respect to a fixed abelian subgroup , and demonstrate a relationship with representations of induced f…
Quantum structures from association schemes
Radhakrishnan Balu
Starting from an association scheme induced by a finite group and the corresponding Bose-Mesner algebra we construct quantum Markov chains (QMC), their entangled versions, and inte…
