Abstract

This paper extends the concept of filter on X into (X, f), where X is a finite underlying set and f is a symmetric submodular function from $$2^X$$ to N. Then, we show a cryptomorphism between a free ultrafilter and co-tangle on (X, f). The paper also provides game-theoretical interpretations of a branch decomposition tree and a free ultrafilter on (X, f).
