Dynamic Programming Equation in the Viscosity Sense.- 7. Weintroduce a new dynamic programming principle and prove that the value function of the stochastic target problem is a discontinuous viscosity solution of the associated dynamic programming equation. 6 and Sect. stochastic target problem in the terminology of [25, 26]. AB - In this paper, we define and study a new class of optimal stochastic control problems which is closely related to the theory of backward SDEs and forward-backward SDEs. it agrees with the solution to the stochastic target problem. By suitably increasing the state space and the controls, we show that this problem can be converted into a stochastic target problem, i.e. Introduction to Viscosity Solutions.- 6. The boundary conditions are also shown to solve a first order variational inequality in the discontinuous viscosity sense. The boundary conditions are also shown to solve a first … This is an extension of [9] and [10] where the set Uwas assumed to be bounded, see also [2] for the case of jump di usions. By Ludovic Moreau. We introduce a new dynamic programming principle and prove that the value function of the stochastic target problem is a discontinuous viscosity solution of the associated dynamic programming equation. We introduce a new dynamic programming principle and prove that the value function of the stochastic target problem is a discontinuous viscosity solution of the associated dynamic programming equation. Here the theory of viscosity solutions plays a crucial role in the derivation of the dynamic programming equation as the infinitesimal counterpart of the corresponding geometric dynamic programming equation. 1.1. The controlled process (Xν, Yν) takes values in ℝd × ℝ and a given initial data for Xν(0).

This extension is crucial for our analysis of the stochastic target problem under controlled probability, and under controlled loss. 7, and the section on mean curvature flow, Sect. Solving Control Problems by Verification.- 5. This dynamic programming prin Problem formulation. Interest Rate Models An Infinite Dimensional Stochastic Analysis Perspective.

The optimal control problem under stochastic target constraint. the stochastic target problem in the present context of possibly unbounded controls. All rights reserved. Series Title: Fields Institute monographs, v. 29. 2. Saintier, Nicolas. In this section, we study a special class of stochastic target problems which avoids facing some technical difficulties, but reflects in a transparent way the main ideas and arguments to handle this new class of stochastic control problems. Stochastic target problems, dynamic programming, and viscosity solutions. This provides a unique characterization of the value function which is the minimal initial data for Yν. keywords = "Discontinuous viscosity solutions, Dynamic programming, Forward-backward SDEs, Stochastic control". DOI identifier: 10.1137/100802268. In the first part of the volume, standard stochastic control problems … problems to standard stochastic target problems. Provides a self-contained presentation of the recent developments in Stochastic target problems which cannot be found in any other monograph; Approaches quadratic backward stochastic differential equations following the point of view of Tevzadze and presented in a way to … Stochastic Target Problems --8. N1 - Copyright: In this paper, we define and study a new class of optimal stochastic control problems which is closely related to the theory of backward SDEs and forward-backward SDEs. journal = "SIAM Journal on Control and Optimization". We next address the class of stochastic target problems which extends in a nontrivial way the standard stochastic control problems. This provides a unique characterization of the value function which is the minimal initial data for Yν. In [25], it is shown that the value function of this target problem satisfies a geometric dynamic program-ming principle (GDP) and, consequently, is a discontinuous viscosity solution of anassociatedHamilton–Jacobi–Bellmanequation. In Chapters II-V, we study different stochastic target problems in various setup.
