Dynamics of stochastic microorganism flocculation models
Alexandru Hening, Nguyen T. Hieu, Dang H. Nguyen +1
In this paper we study the dynamics of stochastic microorganism flocculation models. Given the strong influence of environmental and seasonal fluctuations that are present in these…
Population dynamics under random switching
Alexandru Hening, Siddharth Sabharwal
Populations interact non-linearly and are influenced by environmental fluctuations. In order to have realistic mathematical models, one needs to take into account that the environm…
Stochastic nutrient-plankton models
Alexandru Hening, Nguyen Trong Hieu, Dang Hai Nguyen +1
We analyze plankton-nutrient food chain models composed of phytoplankton, herbivorous zooplankton and a limiting nutrient. These models have played a key role in understanding the…
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…
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…
