Mathematical modelling has long provided critical insights into the complex interactions between predators and their prey. Traditional approaches, such as the Lotka–Volterra model, lay the foundation ...

Why should investors pay attention to cycles? For the same reason farmers pay attention to seasons. It is pointless for a farmer to try to harvest in the spring (or plant in the fall). Investors, too, ...

This paper presents a general equilibrium model of renewable resource and population dynamics related to the Lotka-Volterra predator-prey model, with man as the predator and the resource base as the ...

In this investigation, we will examine the effects of competition for resources on reproductive output within and between two species of parasitoid wasps. Ecological communities are composed of ...

In this paper, we consider positive solutions of a predator-prey model with diffusion and under homogeneous Dirichlet boundary conditions. It turns out that a certain parameter m in this model plays a ...

The same mathematical models used to study the hunting range of lions have many other applications—they describe the flight patterns of honeybees. And now researchers say these math models can help ...

Researchers from the HSE Faculty of Economic Sciences have proposed a mathematical model that describes the course of the COVID-19 pandemic, taking into account the restrictions applied in different ...
