m](A), and therefore it is itself a stable quasiorder, which proves (i).
But [phi](R) need not be a quasiorder even if R is.
M] is a stable quasiorder we get the following sequence of [T.
We call a system of relations [rho] a fully invariant system of stable quasiorders if it satisfies conditions (i) and (ii) of Lemma 3.
Another example of a fully invariant system of stable quasiorders of finite index is given by the kernel of the content function [alpha].
Further, let [rho] be a fully invariant system of stable quasiorders.
Thus, we can define for each fully invariant system of stable quasiorders [rho] and every finite monoid M the relation [[rho].
