Outline of Final Research Achievements

The game-theoretic probability established by Shafer and Vovk in their book "Probability and Finance: It's Only a Game!" constructs the whole framework of probability theory based on a betting game between two players without using the measure theory. In this study, we mainly considered continuous time games and obtained results on refinements of the law of the iterated logarithm and the efficiency of Bayesian betting strategies.

Academic Significance and Societal Importance of the Research Achievements

ゲーム論的確率論は賭けゲームに基づく理論であるために、数学的な証明には具体的な賭け戦略を考察することとなる。このため、標準的な測度論的証明とかなり異なるものとなり、証明がより具体的になるとともに、確率論の古典的な法則についても新たな知見が得られる。また数理ファイナンスにおける議論とも共通点があり、数理ファイナンスの観点からも興味のある結果が得られる。本研究でも、例えば重複対数法則の精緻化において、既存の測度論的確率論の証明とは全く異なる視点が得られた。
