Abstract

‎‎We introduce the notion of a minimal generator G for the coded system X; that is a generator for coded system X whenever uG‎, ‎then uW()‎. ‎Such an X is called \emph{minimally‎ ‎generated system}‎. ‎We ‎aim ‎to‎ introduce a class of minimally‎ ‎generated subshifts generated by some certain synchronizing blocks‎. ‎These systems are precisely the tool that will enable us to show that for such subshifts X‎, ‎each xX‎‎ can be written uniquely as‎ x=v1v0v1v2, where {,v1,v0,v1,v2,}G.‎‎‎‎‎‎ ‎Shows that the converse of that proposition isn't necessarily true‎.‎ {\color{red}‎ ‎‎‎‎‎‎We will show which of the components of the Kreiger graph of such a subshift could be a candidate to be suitable for a Fischer cover‎.‎‎‎‎‎ }
