# An important application of reversed martingales is provided by De Finetti's theory of exchangeable random variables. To describe his theory, let E denote the group of all finite permutations of Z +. That is, an element 7r of E is an isomorphism of Z + that moves only a finite number of integers.

On de Finetti’s Theory of Probability and its Application to Quantum Mechanics Joseph Berkovitz+* IHPST, University of Toronto joseph.berkovitz@utoronto.ca Abstract. Bruno de Finetti is one of the founding fathers of the subjectivist school of probability, where probabilities are interpreted as rational degrees of belief.

Finetti Bruno De - 1989 - Erkenntnis 31 (2-3):169 - 223. De Finetti’s theory of probability is one of the foundations of Bayesian theory. De Finetti stated that probability is nothing but a subjective analysis of the likelihood that something will happen and that that probability does not exist outside the mind.

A Short Historical Note De Finetti published his writings over the years 1926–1983, and developed a large part of his approach to probability theory in the ﬁrst thirty years. 2015-02-17 So de Finetti’s advocacy of the desideratum leads one to objective, rather than subjective, Bayesianism. Note here that the geometry of the space of probability functions de-pends on the loss function, in the sense that the notion of distance varies according to the loss function. As a default loss function, de Finetti con-sidered Brier score. Bruno de Finetti” This concludes our three-part series on de Finetti’s preface. References.

De Finetti maintained that rationality requires that degrees of belief be coherent, and he argued that the whole of probability theory could be derived from these coherence conditions. De Finetti’s interpretation of probability has been highly influential in science.

### wards, de Finetti accepted a position in Rome, at the Istituto Centrale di Statistica, presided over, at that time, by an outstanding Italian statistician: Corrado Gini. De Finetti worked there until 1931. In those years, he laid the foundations for his principal con-tributions to probability theory and statistics: the
