| Abstract: | Given the set of vertical pairs of matrices  keeping the subspace  invariant, we compute miniversal deformations of a given pair when it is observable, and the subspace  is marked. Moreover, we obtain the dimension of the orbit, characterize the structurally stable vertical pairs, and study the effect of each deformation parameter. Copyright © 2013 John Wiley & Sons, Ltd. |
