Mean-square exponential stability of exact and numerical solutions for neutral stochastic delay differential equations with Markovian switching
Jina Yang, Ky Quan Tran
This paper investigates the mean-square exponential stability of neutral stochastic differential delay equations (NSDDEs) with Markovian switching. The analysis addresses the compl…
Harvesting of a stochastic population under a mixed regular-singular control formulation
K. Q. Tran, L. T. N. Bich, George Yin
This work focuses on optimal harvesting-renewing for a stochastic population. A mixed regular-singular control formulation with a state constraint and regime-switching is introduce…
The effects of random and seasonal environmental fluctuations on optimal harvesting and stocking
Alexandru Hening, Ky Q. Tran, Sergiu C. Ungureanu
We analyze the harvesting and stocking of a population that is affected by random and seasonal environmental fluctuations. The main novelty comes from having three layers of enviro…
Optimal Control and Numerical Methods for Hybrid Stochastic SIS Models
Ky Tran, George Yin
This work focuses on optimal controls of a class of stochastic SIS epidemic models under regime switching. By assuming that a decision maker can either influence the infectivity pe…
Harvesting and seeding of stochastic populations: analysis and numerical approximation
Alexandru Hening, Ky Tran
It is well known that excessive harvesting or hunting has driven species to extinction both on local and global scales. This leads to one of the fundamental problems of conservatio…
Harvesting of interacting stochastic populations
Alexandru Hening, Ky Quan Tran, Tien Trong Phan +1
We analyze the optimal harvesting problem for an ecosystem of species that experience environmental stochasticity. Our work generalizes the current literature significantly by taki…
