  1. 1. Optimal stopping, incomplete information, and stochastic games

    Författare :Yuqiong Wang; Erik Ekström; Sören Christensen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optimal stopping; sequential analysis; incomplete information; asymmetric information; stochastic filtering; Dynkin games; tug-of-war games; Mathematics; Matematik;

    Sammanfattning : This thesis contains six papers on the topics of optimal stopping and stochastic games. Paper I extends the classical Bayesian sequential testing and detection problems for a Brownian motion to higher dimensions. We demonstrate unilateral concavity of the cost function and present its structural properties through various examples. LÄS MER
