Resumen:
We elaborate on the deviation of the Jordan structures of two linear relations that are finite-dimensional perturbations of each other.Then, after representing matrix pencils via linear relations, we apply our results to one-dimensional perturbations of singular and regular matrix pencils. This technique allows for both proving known results for regular pencils as well as new results for singular ones.
