Positive semidefinite zero forcing [PDF]

open access: yesLinear Algebra and Its Applications, 2013
The positive semidefinite zero forcing number Z+(G) of a graph G was introduced in [4]. We establish a variety of properties of Z+(G): Any vertex of G can be in a minimum positive semidefinite zero forcing set (this is not true for standard zero forcing).

Fractional zero forcing via three-color forcing games [PDF]

open access: yesDiscrete Applied Mathematics, 2016
An r-fold analogue of the positive semidefinite zero forcing process that is carried out on the r-blowup of a graph is introduced and used to define the fractional positive semidefinite forcing number.
