## Objectives of the workshop

This workshop will bring together researchers studying game-theoretic probability with others who have also been studying probability-free frameworks and frameworks depending on weak probabilistic assumptions. This year's workshop will have "Probability-free finance" as its area of special emphasis. Previous workshops with the same title, Game-Theoretic Probability and Related Topics, were held in 2006, 2008, and 2012 in Tokyo and in 2010 in the London area.

Traditionally, this series of workshops have included the following topics related to game-theoretic probability: imprecise probabilities, prequential statistics, on-line prediction, and algorithmic randomness. Another related topic is conformal prediction. However, this year, due to the emphasis on probability-free finance, not all of them will be represented.

The objective of the workshop will be to make researchers using different approaches to probability-free finance (both mathematical and philosophical) aware of each others' work and to explore commonalities between their frameworks and points of view.
