The Department, founded in 2007, focuses on research in Biomathematics. The modelling effort exploits mathematical methodologies based on evolutionary game theory, differential and difference equations, stochastic processes and rule-based computer simulations of interacting individuals.
Head of the Department: Prof. Vlastimil Křivan
The Institute of Mathematics and Biomathematics offers Bachelor’s and Master’s Programmes in Teaching of Mathematics and a Bachelor’s programme in Applied Mathematics. The current research of the Institute focuses on applied mathematics in biological and technical sciences, differential equations, numerical methods, and geometry.
The research in mathematical biology, conducted jointly with the Biology Centre of the Czech Academy of Sciences, focuses on the development and analysis of mathematical models of behavioural, population, and evolutionary ecology with the aim of understanding mechanisms regulating species biodiversity. Mathematical methodologies based on game theory, differential and difference equations, stochastic processes, and rule-based computer simulations of interacting individuals are used.
The institute pursues research in the technical applications of mathematics. In particular, this research focuses on the theory and numerical solution of nonlinear differential equations used in the mechanics of solids including elastoplasticity and damage processes in materials. These methods are based on finite element computations, fast solution of linear systems of equations, and error control in terms of posteriori error estimates.
The main subject of this research is the representation theory of Lie groups and algebras, parabolic geometries and their applications in control theory. These applications include description of kinematic spaces and optimal movement of robots, e.g. tri-segment snake.
We study the qualitative behaviour of ordinary and partial differential equations. In particular, we focus on the existence and bifurcation of non-trivial solutions with unilateral boundary conditions. We also use Filippov solutions of ordinary differential equations to solve models arising in biology.
