ON THE BAIRE CLASSIFICATION OF CONDITIONAL INDICES OF LINEAR SYSTEMS
摘要
We systematically present the construction proposed by V. M. Millionshchikov, which allows, given a characteristic of the growth of solutions to a linear system, to obtain a set of additional characteristics each of which is responsible for the behavior of subspaces of solutions of the respective dimension. We establish a sufficient condition for these characteristics to belong to the second Baire class in the compact-open topology on the space of linear systems.
