Abstract: | By 6], the dualities between
and
, whereX andW are two sets and
(i.e., the mappings
satisfying
for all
and all index setsI), can be represented with the aid of functions
. Here we show that they can be also represented with the aid of functions
, whereR = (– , + ). As an application, we show that every duality
is completely determined by a suitable duality between 2
X ×R
and 2
W ×R
(i.e., a mapping ![Gamma](/content/n36754260tj0300v/xxlarge915.gif) 2
