This bachelor’s thesis deals with the analysis of nonlinear dynamical systems with a focus on deterministic chaos. The theoretical part introduces the fundamental concepts of dynamical systems theory and chaos quantifiers, in particular Lyapunov exponents, Kolmogorov entropy, and fractal dimension. The practical part focuses on the numerical analysis of selected models, namely the Lorenz and Rössler systems. Algorithms implemented in the Python programming language are used for computations and mutual comparison of different numerical methods. These algorithms are used to determine Lyapunov exponents, the Kaplan–Yorke dimension, and Kolmogorov entropy. The results demonstrate the sensitivity of these quantifiers to the choice of numerical method and the setting of its parameters, and indicate the presence of chaotic behavior in the studied systems. The thesis thus provides an overview of chaos detection methods and their practical application in the analysis of dynamical systems.
