On nonatomic submeasures on N. III
نویسندگان
چکیده
In our earlier paper (Arch. Math. 91 (2008), 76–85), we proved that if F is a sequence of finite nonempty subsets of N such that a certain quantity t(F ) is finite, then the associated submeasure dF on N is nonatomic. In the present note, we give two curious characterizations of the set of such F ’s. Mathematics Subject Classification (2000). 05A17, 11B05, 28A12.

On distance distribution functions-valued submeasures related to aggregation functions
Probabilistic submeasures generalizing the classical (numerical) submeasures are introduced and discussed in connection with 13 some classes of aggregation functions. A special attention is paid to triangular norm-based probabilistic submeasures and more general semi-copula-based probabilistic submeasures. Some algebraic properties of classes of such submeasures are also studied. 15 © 2012 Else...
متن کاملOn a Certain Class of submeasures Based on Triangular Norms
In this paper we study a generalization of a submeasure notion which is related to a probabilistic concept, especially to Menger spaces where triangular norms play a crucial role. The resulting notion of a τT -submeasure is suitable for modeling those situations in which we have only probabilistic information about the measure of the set. We characterize a class of universal τT -submeasures (i....
