Tiivistelmä
We introduce quasiminimal subshifts, subshifts having only finitely many subsystems. With N-actions, their theory essentially reduces to the theory of minimal systems, but with Z-actions, the class is much larger. We show many examples of such subshifts, and in particular construct a universal system with only a single proper subsystem, refuting a conjecture of [3]. (C) 2017 Elsevier Inc. All rights reserved.
