Mathematical analysis in one and several variables, Linear Algebra and a first course on Differential Equations and modeling.
This subject is the second part of a two semesters course of introduction to ordinary differential equations (ODE). It has both theoretical and applied sides. It is aimed that the students know and are able to apply the concepts of the qualitative theory of ordinary planar differential equations and also that they have a basic knowledge of the paradigmatic partial differential equations. During this semester we will apply many of the results established and studied in the first course on ODE and at the same time we will introduce new tools for studying the mentioned differentiated equations.
This subject is structured in two parts. The first one is about the qualitative theory of ordinary differential equations, with special emphasis on planar autonomous systems. It is an introduction of which later can be studied in more depth in the course "Dynamical systems". The second is a first study of the most famous partial differential equations and also has continuity in the course "Partial differential equations".
3.1 Autonomous systems in the plane.
3.1.1. Autonomous systems in R^n. Geometric interpretation. Structure of the orbits. First integrals. Invariant surfaces. Phase portraits and conjugation.
3.1.2. Integrable systems. Phase portrait of planar integrable systems: potential systems, Hamiltonian systems, the model of Lotka-Volterra.
3.1.3. Non-integrable systems: flow box theorem, qualitative analysis of equilibrium points, limit behavior of the orbits, Bendixson-Poincaré theorem, Lyapunov functions. Limit cycles. Criterion of Bendixon-Dulac. Models of ecology. Van der Pol system.
3.2 First order partial differential equations.
3.2.1. Introduction to partial differential equations(PDE).
3.2.2. Linear and quasi-linear PDE of first order.
3.3 Second order partial differential equations.
3.3.1. The wave equation on an infinite string. D'Alembert's formula. Boundary value problems.
3.3.2. The heat equation. The case of an finite bar.
3.3.3. Separation of variables and Fourier series.
3.3.4. Laplace's equation.
The objective of the classes of theory, problems and practices is to give students the most basic knowledge of the equations in partial derivatives and their applications.
Annotation: Within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.

There will be two partial exams during the course, one in the middle of the course and the other at the end. Also the students must solve a problem with the
help of the computer. If the assessement of the first partial is EP1, of the second partial is EP2, and the assessement of the pratical exercise is P, the final note
will be F=(4EP1+4EP2+2P)/10, but for pass this course it is necessary that P>=4.
If F<5 the student will have a final exam (FE), the assessement of this final exam is (8FE+2P)/10, again for pass this course it is necessary that P>=4.
