Aim of the course

The main aim of this course is to familiarize students with the theory of ordinary differential equations, with particular emphasis on the qualitative theory.

Prerequisites

Mathematical Analysis 1 and 2, Linear Algebra 1 and 2, Mathematical Software.

Scope

  1. Ordinary differential equations - basic definitions and theorems.
  2.  Skalar autonomous equations. One-dimensional phase portraits.
  3.  Dynamical interpretation of systems of ODE. Autonomous systems. Phase trajectories and phase portraits. Flows and orbits. First integrals.
  4.  Systems of linear ordinary differential equations. Methods of solving of homogeneous and inhomogeneous systems of linear equations. Classification and stability of critical points of systems of linear ODE in the plane. Phase portraits.
  5.  Systems of nonlinear ordinary differential equations. Local phase portraits. Linearization, Grobman-Hartman theorem. Classification and stability of critical points of systems of nonlinear ODE in the plane. Global phase portraits.
  6.  Periodic orbits and limits cycles. Limits sets. Poincaré-Bendixson theorem.
  7. Elements of the stability theory. Lyapunov stability. Hurwitz theorem. Lyapunov function and fundamental stability theorems.
  8. Bifurcations and chaos. Hopf bifurcation. The Lorenz model.
  9. Some differential models in physics, biology, medicine and economics.

Assignment conditions

Class : learning outcomes will be verified through homeworks and test consisted of exercises of different degree of difficulty. A grade determined by the sum of points from these homeworks and test is a basis of assessment.

Laboratory: learning outcomes will be verified through  test consisted of exercises of different degree of difficulty. A grade determined by the sum of points from the test is a basis of assessment.
Lecture: final exam. A grade determined by the sum of points from that exam is a basis of assessment.
A grade from the course is consisted of the grade from laboratory (20%), the grade from classes (30%) and the grade from the final exam (50%). To take a final exam, students must receive a positive grade from classes. To attain a pass in the course students are required to pass the final exam.
