Some drifts on posets and its application to fuzzy subalgebras

In this paper, given a poset (X,\leq), we introduce some  drifts on a groupoid (X,*) with respect to (X,\leq), and we obtain several properties of these drifts related to the notion of Bin(X). We discuss some connections between fuzzy subalgebras and upward drifts.
