 Aims This course is an introduction in the mathematical modeling. There are presented basic notions of mathematical modeling process in order to analyse, study and construct mathematical models.
 Content I. Mathematical modelling process 1. Introduction: Important steps in the mathematical history 2. Relation between mathematics and its applications 3. Mathematical modelling process 4. Simple mathematical models: a) Transports problem; b) Fibonacci's problem; c) Bank interest; d) Marketing expenses optimation II. Dynamical systems 1. The notion of dynamical system 2. Dynamical systems generated by difference equations 3. Stationary steady, stability III. Discrete mathematical models 1. Linear difference equations with constant coeficients 2. Linear systems of difference equations with constant coeficients 3. Discrete mathematical models. The logistic difference equation, discrete multispecies models IV. Populations dynamics 1. Continuous dynamical systems 2. Autonomuous systems, stability of equilibrium solutions 3. Mathematical models for a population dynamics (Malthus, Verhulst, harvesting models) 4. Multispecies models (prey-predator, competition, symbiosis) V. Mathematical models in epidemiology 1. Epidemiological models of SIR and SIRS type 2. Models in study of spreading an infectious desease.
