# Exchangeable choice functions

## TL;DR

This paper explores modeling exchangeability using choice functions, establishing a connection to de Finetti's theorem and providing a framework for finite and countable cases.

## Contribution

It introduces a novel approach to represent exchangeability through choice functions, extending classical results to new contexts.

## Key findings

- Exchangeability modeled via choice functions
- De Finetti's Representation Theorem extended to finite and countable cases
- Framework for structural assessment of uncertain sequences

## Abstract

We investigate how to model exchangeability with choice functions. Exchangeability is a structural assessment on a sequence of uncertain variables. We show how such assessments are a special indifference assessment, and how that leads to a counterpart of de Finetti's Representation Theorem, both in a finite and a countable context.
