Regularity properties for general HJB equations. A BSDE method [PDF]

open access: yes, 2011
In this work we investigate regularity properties of a large class of Hamilton-Jacobi-Bellman (HJB) equations with or without obstacles, which can be stochastically interpreted in form of a stochastic control system which nonlinear cost functional is ...

Model order reduction approaches for infinite horizon optimal control problems via the HJB equation

open access: yes, 2016
We investigate feedback control for infinite horizon optimal control problems for partial differential equations. The method is based on the coupling between Hamilton-Jacobi-Bellman (HJB) equations and model reduction techniques.

Model Ambiguity versus Model Misspecification in Dynamic Portfolio Choice

open access: yesThe Journal of Finance, Volume 81, Issue 3, Page 1741-1795, June 2026.
ABSTRACT We study aversion to model ambiguity and misspecification in dynamic portfolio choice. Risk‐averse investors (relative risk aversion γ>1$\gamma > 1$) fear return persistence, while risk‐tolerant investors (0<γ<1$0<\gamma <1$) fear mean reversion, when confronting model misspecification concerns of identically and independently distributed (IID)

Image Restoration via the Integration of Optimal Control Techniques and the Hamilton–Jacobi–Bellman Equation

open access: yesMathematics
In this paper, we propose a novel image restoration framework that integrates optimal control techniques with the Hamilton–Jacobi–Bellman (HJB) equation.

Stochastic HJB Equations and Regular Singular Points [PDF]

open access: yes, 2018
IIn this paper we show that some HJB equations arising from both finite and infinite horizon stochastic optimal control problems have a regular singular point at the origin. This makes them amenable to solution by power series techniques.

Well-posedness and regularity of the Cauchy problem for nonlinear fractional in time and space equations

open access: yes, 2014
The purpose is to study the Cauchy problem for non-linear in time and space pseudo-differential equations. These include the fractional in time versions of HJB equations governing the controlled scaled CTRW.

Dynamic Reactivity: Reversible Reaction of a Phosphinine–Borane Adduct With Water and Double Hydrophosphination

open access: yesChemistry – A European Journal, Volume 32, Issue 19, 22 May 2026.
A phosphinine–borane Lewis pair shows a dynamic mode of water addition, revealing reversible and regioselective transformations that expand the reactivity of aromatic phosphorus heterocycles and open pathways to stimuli‐responsive systems for catalysis, small‐molecule activation, and functional materials.

Stochastic control problems for systems driven by normal martingales

open access: yes, 2008
In this paper we study a class of stochastic control problems in which the control of the jump size is essential. Such a model is a generalized version for various applied problems ranging from optimal reinsurance selections for general insurance models ...

Mean-Variance Portfolio Selection for Defined-Contribution Pension Funds with Stochastic Salary

open access: yesThe Scientific World Journal, 2014
This paper focuses on a continuous-time dynamic mean-variance portfolio selection problem of defined-contribution pension funds with stochastic salary, whose risk comes from both financial market and nonfinancial market. By constructing a special Riccati

Optimal investment and consumption for pairs trading financial markets on small time interval

open access: yes, 2018
In this paper we consider a pairs trading financial market with the spread of risky assets defined by the Ornstein-Uhlenbeck (OU) process. We implement an optimal strategy for power utility functions for investment/consumption problem.
