Seminar at VU Faculty of Physics: Brief introduction into the Physics of Risk

Topic: "Physics is not a risk: Brief introduction into the Physics of Risk"

Speaker: Aleksejus Kononovicius

Briefly: Social sciences have accomplished many different things. Yet it should be evident that there is a place for improvements - to look into the old and new social problems a bit differently. As many of the social problems are strongly non-linear and very complex, the physicists' point of view is very useful. This, new, point of view is known as Physics of Risk.

When? 18th of October, 17:00.

Where? VU Faculty of Physics (Saulėtekio al. 9, III rūmai, Vilnius), 201 auditorium.

Organized by: VU Faculty of Physics Students Scientific Association.

Agent-based prey-predator model

The simplest ecological system can be constructed from the two interacting species, e.g., prey and predator. This kind of system is very interesting in the terms of Physics of Risk primarily because it is nonlinear [1], and due to being real life example of competition (conflict). Also there are few known simple models for the prey-predator interaction. Among them there are both macroscopic, Lotka-Volterra equations, and microscopic, agent-based, models. In this text we continue the previous discussion by considering the agent-based model.

We will start our discussion from the macroscopic Lotka-Volterra model.
