Weyl-Titchmarsh Theory for Sturm-Liouville Operators with Distributional Potentials
Jonathan Eckhardt, Fritz Gesztesy, Roger Nichols +1
We systematically develop Weyl-Titchmarsh theory for singular differential operators on arbitrary intervals associated with rather general differential…
Zero forcing parameters and minimum rank problems
Francesco Barioli, Wayne Barrett, Shaun M. Fallat +5
The zero forcing number Z(G), which is the minimum number of vertices in a zero forcing set of a graph G, is used to study the maximum nullity / minimum rank of the family of symme…
Response to perturbations for granular flow in a hopper
John F. Wambaugh, John V. Matthews, Pierre A. Gremaud +1
We experimentally investigate the response to perturbations of circular symmetry for dense granular flow inside a three-dimensional right-conical hopper. These experiments consist…
Entanglement Evolution in the Presence of Decoherence
Jin Wang, Herman Batelaan, Jeremy Podany +1
The entanglement of two qubits, each defined as an effective two-level, spin 1/2 system, is investigated for the case that the qubits interact via a Heisenberg XY interaction and a…
