Abstract

Probably the distinguishing concept in incomplete information analysis is that of "boundary": in fact a boundary is precisely the region that represents those doubts arising from our information gaps. In the paper it is shown that the rough set analysis adequately and elegantly grasps this notion via the algebraic features provided by co-Heyting algebras.
