Kuznetsov independence of variables X and Y means that, for any pair of bounded functions f(X)f(X) and g(Y)g(Y), E[f(X)g(Y)]=E[f(X)]⊠E[g(Y)]E[f(X)g(Y)]=E[f(X)]⊠E[g(Y)], where E[⋅]E[⋅] denotes interval-valued expectation ...

This paper analyzes concepts of independence and assumptions of convexity in the theory of sets of probability distributions. The starting point is Kyburg and Pittarelli's discussion of "convex Bayesianism" (in particular ...

We introduce the notion of star cluster of a simplex in a simplicial complex. This concept provides a general tool to study the topology of independence complexes of graphs. We use star clusters to answer a question arisen ...

The experience with the concept of function has shown countles obstacles to his understanding , however reseachers in mathematics educatio have provided different stages of evolution of the concept in the hope of contributing ...

This paper builds on earlier studies of central bank independence (CBI);, making a comparison of the rankings of central banks for 15 countries through three different indices. The analysis reveals that there is no ...
