Regularization in multistage cooperitive games
Maria Dementievan väitöskirja käsittelee yhteistyöpelien teoriaa ja niiden ratkaisemista. Työssä pyritään kuvaamaan peliteorian ongelmien ratkaisujoukon ns. aliytimen ominaisuuksia. Työn päähuomio on kiinnitetty monivaiheisten yhteistyöpelien ratkaisujen aikakonsistenttisyyteen liittyvään problematiikkaan.Tämä problematiikka liittyy läheisesti proseduuriin, joka pyrkii kohdentamaan hyötyä pelaajille pelin jokaisessa vaiheessa. Työssä käsitellään myös ns. supistettua peliominaisuutta ja dynaamista konsistenttisyyttä liittyen erääseen tunnetun Davis-Maschler-pelin muunnelmaan. Tämän muunnelman aikakonsistettisyystarkasteluun esitetään uusi lähestymistapa. This thesis deals with solutions of cooperative games. We describe the properties of the subcore and grand subcore. The main part of the work is dedicated to the time-consistency problem of a multistage cooperative games solution. This problem is closely connected with the imputation distribution procedure, which allocates the common benefit among the players at every step of the game. The reduced game property (or consistency) is also considered with respect to the modified Davis-Maschler-reduced game, and the property of dynamic consistency is introduced and investigated. We use a new approach to the time-consistency problem. The problem of minimal reduction is stated and we apply the results to regularization of the cooperative dynamic game in the case of no time-consistent imputations from the core in the balanced multistage cooperative game with transferable utility. At the end of the work a multistage cooperative model of the Kyoto Protocol realization is constructed and corresponding imputation distribution procedures are suggested for the game.

Uniform measure density condition and game regularity for tug-of-war games
Heino, Joonas (International Statistical Institute; Bernoulli Society for Mathematical Statistics and Probability, 2018)We show that a uniform measure density condition implies game regularity for all 2 < p < ∞ in a stochastic game called “tug-of-war with noise”. The proof utilizes suitable choices of strategies combined with estimates for ... -
Local regularity estimates for general discrete dynamic programming equations
Arroyo, Ángel; Blanc, Pablo; Parviainen, Mikko (Elsevier, 2022)We obtain an analytic proof for asymptotic Hölder estimate and Harnack's inequality for solutions to a discrete dynamic programming equation. The results also generalize to functions satisfying Pucci-type inequalities for ... -
Asymptotic C1,γ-regularity for value functions to uniformly elliptic dynamic programming principles
Blanc, Pablo; Parviainen, Mikko; Rossi, Julio D. (Springer, 2022)In this paper we prove an asymptotic C1,γ-estimate for value functions of stochastic processes related to uniformly elliptic dynamic programming principles. As an application, this allows us to pass to the limit with a ...
