One-sided classiiers are computable devices which read the characteristic function of a set and output a sequence of guesses which converges to 1 ii the set on the input belongs to the given class. Such a classiier is two-sided if the sequence of its output in addition converges to 0 on sets not belonging to the class. The present work obtains the below mentioned results for one-sided classes (...

The present paper considers a discrete analog of the parking problem. Let n be an integer. If > 1, then we randomly locate interval (t, t + 1) with integer endpoints on segment [0, n]. Thus, original is divided into two: t] and [t n], each them further considered separately likewise one. phrase “randomly” in this problem means that uniformly distributed set {1, . , − 1} random variable. process...

In this paper, I consider eight basic fallacies that can arise from using conventional wisdom from one-sided markets in two-sided market settings. These fallacies are illustrated using statements made in the context of regulatory investigations into credit card schemes in Australia and the United Kingdom. I discuss how these fallacies may be reconciled by proper use of a two-sided market analys...
