On strong shift equivalence over a Boolean semiring

WebOct 2, 2012 · For example the Integer Semiring is defined over the integers where + and * are the standard operations from arithmetic and zero and one are the integers 0 and 1. A more exotic example is the Boolean Semiring, which is defined over the values True and False, where + is logical OR, * is logical AND, zero is False, and one is True. WebReplacing R by the Boolean semiring B. One can go further and replace commutative ring R by a commutative semiring. A semiring has multiplication and addition but no subtraction, in general. It turns out that replacing C by a commutative semiring (for example, Boolean semiring B) adds a twist and a different kind of complexity to the theory. cement sheet villaboardWebSep 19, 2008 · We prove that for many Boolean matrices strong shift equivalence is characterized by shift equivalence and a trace condition.
