Representation of continuous associative functions.

Barbara Baccheli (1986)

Stochastica

Similarity:

Strengthened forms of Ling's representation theorem concerning a class of continuous associative functions are given: Firstly the monotonicity condition is removed. Then the associativity condition is replaced by the power associativity.

Some problems of measure theory which are related to economic theory.

Heinz J. Skala (1982)

Stochastica

Similarity:

After a short discussion of the first application of measure theoretic tools to economics we show that it is consistent relative to the usual axioms of set theory that there exists no nonatomic probability space of power less than the continuum. This together with other results shows that Aumann's continuum-of-agents methodology provides a sound framework at least for the cooperative theory. There are, however, other problems in economics where, without further assumptions,...

New metrics for weak convergence of distribution functions.

Michael D. Taylor (1985)

Stochastica

Similarity:

Sibley and Sempi have constructed metrics on the space of probability distribution functions with the property that weak convergence of a sequence is equivalent to metric convergence. Sibley's work is a modification of Levy's metric, but Sempi's construction is of a different sort. Here we construct a family of metrics having the same convergence properties as Sibley's and Sempi's but which does not appear to be related to theirs in any simple way. Some instances are brought out in which...

Kurepa's functional equation on semigroups.

Bruce R. Ebanks (1982)

Stochastica

Similarity:

The functional equation to which the title refers is: F(x,y) + F(xy,z) = F(x,yz) + F(y,z), where x, y and z are in a commutative semigroup S and F: S x S --> X with (X,+) a divisible abelian group (Divisibility means that for any y belonging to X and natural number n there exists a (unique) solution x belonging to X to nx = y).
