Stability and chaotic behaviour of the Lorenz system
Oborná, Eliška ; Nechvátal, Luděk (referee) ; Čermák, Jan (advisor)
This bachelor's thesis analyzes the behavior of the Lorenz's model of convective flow in the atmosphere depending on the Rayleigh number. It offers several methods when analyzing stability of nonlinear systems of the first order autonomous differential equations. Part of the work also consists of introduction to deterministic chaos which appears in dynamic systems with a parameter. The work is supported by graphic interpretation of a stable and chaotic behavior by using the software Maple.

Continuous and discrete models of population biology
Fedorková, Lucie ; Tomášek, Petr (referee) ; Čermák, Jan (advisor)
This thesis analyzes the continuous and discrete logistic model of a single-species population. For both of these models, there are discussed problems of equilibria, their stability and behaviour of the solutions for different initial conditions. In the case of the discrete model, the periodic behaviour of solutions is discussed in detail with respect to change of a parameter characterizing growth of the investigated population. The chaotic behaviour of solutions is mentioned as well. The graphic interpretations of each of the problems are performed using the software MATLAB. The calculations are checked via the software Maple.
