Web4 Representation of inf-lattices The main example of a inf-lattice and of a convexity algebra is the power set P(X) of a non empty set X. It can be proved that any inf-lattice can be represented as a quotient inf-lattice of a power set lattice with respect to a congruence(see [1]).

Then, we have that ( f + g) ( t) = A + B. Hence, sup ( f + g) = sup ( f) + sup ( g). 2: If A and B are not in same x, then f ( p) = A and g ( q) =. Hence, sup ( f + g) ≤ A + B. From 1 and 2, we have that. sup ( f + g) ≤ sup ( f) + sup (. sum of hours in pivot table
