From disorder detection to optimal stopping and mathematical finance

Robert Liptser, Alexander G. Tartakovsky

Research output: Contribution to journalArticlepeer-review


We begin with an overview of the quickest changepoint detection problem with an emphasis on Shiryaev's contributions to the field and show how the development in this area has led to optimal stopping theory. We then proceed to tackle application of optimal stopping and change detection in economics and finance, which has been a focus of Shiryaev's research for years.
