SCHIMPERNA GIULIO FERNANDO (titolare) - 9 ECTS
Prerequisites
In order to follow this course with the due preparation it is necessary to have acquired the basic competences resulting from the courses of the first year, in particular: differential and integral calculus for scalar and vector functions, matrices and linear transformations, sequences and series, power series, complex numbers, differential forms, polar coordinates.
Learning outcomes
Learn the basic results and techniques of the theory of ordinary differential equations and dynamical systems. Be able to apply the methods of the ODE theory to study simple real-world applications and physical models. Acquire skill in manipulation and transforms of complex numbers and understand the first but deep results of complex function theory. Learn the main integration techniques based on the Residue theorem.
Course contents
The course is divided into two parts: the first one is devoted to the theory of ordinary differential equations and systems, with an introduction to the study of dynamical systems. The second part is an introduction to the theory of functions of one complex variable.

Extended summary

Models and examples of ODE's. General results concerning existence, uniqueness, comparison and stability for Cauchy problems. Elementary techniques for solving simple differential equations. Cauchy-Peano's theorem (existence without uniqueness). Linear systems of ODE's: general results and structure, exponential matrix.
Asymptotic behaviour of dynamical systems, stability (linearisation and Lyapunov method).

Examples of complex functions. Differentiability. Power series and contour integrals. Holomorphic functions. Cauchy's theorem. Singularities, Laurent expansion and residues. Cauchy theorem. Application to the evaluation of integrals. Analytic extension. Argument principle. Open mapping theorem. Further geometrical properties of holomorphic functions.
Teaching methods
Lectures and exercise sessions.
The two parts of the course (1 - ordinary differential equationa and 2 - complex analysis) will proceed in parallel (generally 2 or 3 hours per week will be devoted to complex anlysis and the remaining ones to differential equations).
The exercises sessions will be scheduled at the end of each part of the the theory.

Assessment methods
Written and oral test.
The written test will be constituted by a number of exercises. Some of the exercises will have a theoretical character (proofs of simple properties or construction of examples or counterexamples); other ones will be aimed at verifying the acquisition of the basic computational techniques developed in the course (explicit resolution of differential equations or calculus of some integral by complex variable methods).
The oral exam will be aimed at verifying the comprehension of the main results of the theory and the capacity to illustrate them by means of concrete examples.
