Estimates for viscosity solutions of fully nonlinear equations near smooth boundaries
Niklas L. P. Lundström, Marcus Olofsson, Jesper Singh
We reduce the problem of proving decay estimates for viscosity solutions of fully nonlinear PDEs to proving analogous estimates for solutions of one-dimensional ordinary differenti…
Estimates of size of cycle in a predator-prey system II
Niklas L. P. Lundström, Gunnar J. Söderbacka
We prove estimates for the maximal and minimal predator and prey populations on the unique limit cycle in a standard predator-prey system. Our estimates are valid when the cycle ex…
Enhancing Precision with the Local Pivotal Method: A General Variance Reduction Approach
Marcus Olofsson, Anton Grafström, Niklas L. P. Lundström
The local pivotal method (LPM) is a successful sampling method for taking well-spread samples from discrete populations. We show how the LPM can be utilized to sample from arbitrar…
Growth of subsolutions to fully nonlinear equations in halfspaces
Niklas L. P. Lundström
We characterize lower growth estimates for subsolutions in halfspaces of fully nonlinear partial differential equations on the form in terms of solutions t…
How to find simple nonlocal stability and resilience measures
Niklas L. P. Lundström
Stability of dynamical systems is a central topic with applications in widespread areas such as economy, biology, physics and mechanical engineering. The dynamics of nonlinear syst…
Pareto-efficient biological pest control enable high efficacy at small costs
Niklas L. P. Lundström, Hong Zhang, Åke Brännström
Biological pest control is increasingly used in agriculture as a an alternative to traditional chemical pest control. In many cases, this involves a one-off or periodic release of…
Phragmén-Lindelöf theorems and p-harmonic measures for sets near low-dimensional hyperplanes
Niklas L. P. Lundström
We prove estimates of a -harmonic measure, , for sets in which are close to an -dimensional hyperplane , $m \in [0,…
