Discrete Time Optimal Harvesting of Fish Populations with Age Structure
Autor: Wandi Dine, Suzanne Lenhart, Horst Behncke
Publikováno v: Letters in Biomathematics, Vol 1, Iss 2, Pp 193-207 (2014)
We consider an optimal fishery harvesting problem using an age-structured population model with nonlinear recruitment. The motivating example is Atlantic Cod. The goal is to maximize the profit (total gain) of fishing. We seek to find the optimal har

Spectral theory of higher order difference operators
Autor: Horst Behncke, Fredrick Oluoch Nyamwala
Publikováno v: Journal of Difference Equations and Applications. 19:1983-2028
The spectral theory of higher order difference operators is studied by means of asymptotic summation, thereby extending many results of differential operators to the discrete setting. The spectra of degenerate fourth-order operators are also investig

The remainder term in asymptotic summation of linear difference systems
Autor: Horst Behncke
Publikováno v: Journal of Difference Equations and Applications. 19:850-862
Quantitative estimates for the remainder terms in the asymptotic summation of linear difference systems are derived. For example, it is shown that any decay in excess of summability is passed on to the remainder.

Spectral theory of Hamiltonian difference systems with almost constant coefficients
Autor: Horst Behncke
Publikováno v: Journal of Difference Equations and Applications. 19:1-12
The spectral theory for a general linear Hamiltonian difference system with asymptotically constant coefficients is developed with rather mild smoothness conditions for the coefficients. It is shown that the absolutely continuous spectrum is that of
