The centre of a semiring K, written Kc , is the set of elements of K which commutes with all the elements of K. Show that Kc is a sub-semiring of K. 23 I cannot resist the pleasure of quoting P. M. ’ 30 CH. 0 . FUNDAMENTAL STRUCTURES 6 Matrices A matrix is not, properly speaking, a structure in the algebraic sense of the term, as a monoid or semiring is; it is rather a mathematical object, or notational convention, which we recall here because we shall use it frequently, especially from Chapter III onwards.

By two different methods we have constructed two distinct machines which compute the same thing. If these two machines were given to us, from outside, as the result of some process over which we had no control, would we be able to see that they computed the same thing? This question is fundamental. It comes down to knowing to what extent these machines, which are entirely defined by a finite quantity of information, faithfully represent, and in a useful manner, infinite sets (in the example, numbers divisible by 3).

An , b1 , . . , bp ) . This operation is clearly associative, as it has a neutral element: the empty sequence or empty word. 12 The set of non-empty words is written A+ = A∗ \ 1A∗ . The qualifier ‘proper’ is often used as a synonym for different from the empty word or does not contain the empty word. The product on words is not commutative when A contains at least two letters. The definition of product implies that the word f can be written f = (a1 , a2 , . . , an ) = (a1 ) · (a2 ) · · · · · (an ) .
