Course Objective

know:

–      sources of mathematical models, types of models, approaches to their construction and analysis, typical results of analysis of known mathematical models;

be able to:

–      decompose complex processes for modeling, to identify deterministic and stochastic parts, to construct mathematical models in continuous and discrete, one-dimensional and multidimensional cases, with the presence of delay and without it, to find equilibrium positions and analyze the behavior around them;

–      have knowledge of methods of linear approximation, mitigation, estimation, analogies and hierarchies in mathematical modeling.

Course content

Introduction to mathematical modeling (concepts, classification of models, examples).

Sources of mathematical models (fundamental laws of nature, variational principles, analogy method, hierarchical approach, nonlinear models as a consequence of mitigation of assumptions).

Mathematical models of oscillatory occurrences (oscillation of Saturn’s rings, weight on the spring, model of Predator-Victim of Volterra, model of chemical reaction of Lotka, salary and employment, mathematical pendulum, addition of oscillations, nonlinear variants).

Modeling methods leading to DEPD (multidimensional mathematical models, transport equation, continuity equation, Boussinesq equation, Korteweg-De Vries equation, von Foerster model).

Direct and co-ordinated tasks (the model for the spread of air pollution in the atmosphere, the equation of turbulent diffusion, the optimization of the location of pollution sources and emissions in a tight quota policy).

Mathematical models with delay (logistic model, linear analysis of the behavior near the equilibrium position, the model of the restoration of the number of blood cells, the model of the arrhythmia of breathing Shane-Stokes).

Discrete mathematical models (discrete analogues of the logistic model, oscillatory and chaotic solutions, analytical coding).

Modeling of complex processes (strategy of making assumptions in the construction of models, compartmental models and models of the dynamics of epidemics, cellular automata, the model of the dynamics of relations).
