The Inverse Symplectic Eigenvalue Problem of a Graph
Himanshu Gupta, Leslie Hogben, Bryan Shader +1
Symplectic geometry plays an increasingly important role in mathematics, physics and applications, and naturally gives rise to interesting matrix families and properties. One of th…

Zero forcing propagation time intervals and graphs with fixed propagation time
Daniela Ferrero, H. Tracy Hall, Leslie Hogben +2
Zero forcing in a graph refers to the evolution of vertex states under repeated application of a color change rule. Typically the states are chosen to be blue and white, and a forc…

Sharp bounds for product and sum throttling numbers
Ryan Blair, Gabriel Elvin, Veronika Furst +3
Throttling in graphs optimizes a sum or product of resources used, such as the number of vertices in an initial set, and time required, such as the propagation time, to complete a…
