Optimal Stopping and Free-Boundary Problems
The present monograph, based mainly on studies of the authors and their - authors, and also on lectures given by the authors in the past few years, has the following particular aims: To present basic results (with proofs) of optimal stopping theory in both discrete and continuous time using both martingale and Mar- vian approaches; To select a seriesof concrete problems ofgeneral interest from the t- ory of probability, mathematical statistics, and mathematical ?nance that can be reformulated as problems of optimal stopping of stochastic processes and solved by reduction to free-boundary problems of real analysis (Stefan problems). The table of contents found below gives a clearer idea of the material included in the monograph. Credits and historical comments are given at the end of each chapter or section. The bibliography contains a material for further reading. Acknowledgements.TheauthorsthankL.E.Dubins,S.E.Graversen,J.L.Ped- sen and L. A. Shepp for useful discussions. The authors are grateful to T.

A comprehensive treatment of optimal stopping and free-boundary problems ranging from pure theoretical aspects describing methods of solution to specific examples worked out in full detailMarries the three classic problem formulations due to Lagrange (18th century), Mayer (19th century) and Bolza (1913) with the modern problem formulation based on the maximum functional to produce a unifying theoryDeals with the principles of smooth and continuous fit in a unifying wayPresents complete solutions to option problems (American, Russian, Asian) using local time-space calculus and nonlinear integral equationsPresents solutions to problems of optimal prediction of the ultimate maximum opening new avenues for research
