文摘It is known that a minimal prime system is either a subshift or with a connected phase space(Keynes and Newton TransAmMath Soc 217:237-255,1976).We show that a double minimal system is a subshift;this implies immediately that no non-periodic map has 4-fold topological minimal self-joinings.We also prove that a POD system is either uniformly rigid or is a subshift.
