Threshold dynamics and optimal control on an age-structured SIRS epidemic model with vaccination

Mathematical Biosciences and Engineering, 2021
We consider a vaccination control into a age-structured susceptible-infective-recovered-susceptible (SIRS) model and study the global stability of the endemic equilibrium by the iterative method. The basic reproduction number $ R_0 $ is obtained.

Optimal Dividends for a Two-Dimensional Risk Model with Simultaneous Ruin of Both Branches

Risks, 2022
We consider the optimal dividend problem in the so-called degenerate bivariate risk model under the assumption that the surplus of one branch may become negative.

Smooth Value Functions for a Class of Nonsmooth Utility Maximization Problems [PDF]

, 2010
In this paper we prove that there exists a smooth classical solution to the HJB equation for a large class of constrained problems with utility functions that are not necessarily differentiable or strictly concave.

Numerical simulation of collision-free near-shortest path generation for Dubins vehicle via Hamilton–Jacobi–Bellman equation: A case study

Cogent Engineering, 2020
Motivated by modeling an unmanned aerial vehicle at a constant altitude plane above ground level as Dubins vehicle with signed upper-bounded curvature as constrained input and the flight path as Dubins path, the class of flight paths we study is ...
