        >How can one define borders to each local system?

        Local systems have no boundaries in either spatial or temporal sense. A local system is
        just a collection (set) of plural particles. It can extend to any place far from its center
        of mass. This extension does not require time, for in a local system, no time is necessary
        to reach any point of the system. It is an inside-world as our mind.
