Optimal ergodic harvesting under ambiguity
Asaf Cohen, Alexandru Hening, Chuhao Sun
We consider an ergodic harvesting problem with model ambiguity that arises from biology. To account for the ambiguity, the problem is constructed as a stochastic game with two play…
Quasi-stationary distributions of multi-dimensional diffusion processes
Alexandru Hening, Weiwei Qi, Zhongwei Shen +1
The present paper is devoted to the investigation of the long term behavior of a class of singular multi-dimensional diffusion processes that get absorbed in finite time with proba…
Coexistence, extinction, and optimal harvesting in discrete-time stochastic population models
Alexandru Hening
We analyze the long term behavior of interacting populations which can be controlled through harvesting. The dynamics is assumed to be discrete in time and stochastic due to the ef…
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…
The competitive exclusion principle in stochastic environments
Alexandru Hening, Dang H. Nguyen
In its simplest form, the competitive exclusion principle states that a number of species competing for a smaller number of resources cannot coexist. However, it has been observed…
