Overview

The course gives a basic knowledge on the weak formulation of non-linear evolution equations, with particular emphasis on reaction-diffusion equations and damped wave equations. When the problem is well posed and the solution operator satisfies suitable properties, the student will be able to set the model in the framework of infinite dimensional dynamical systems. Whenever possible, the longtime behavior of the system will be described by global attractors.

Admission requirements

Prerequisites are Calculus 1 and 2, Theory of Banach and Hilbert spaces, basic theory of Lebesgue spaces. The knowledge of Sobolev spaces is recommended but not mandatory.

Course contents

The main topics are: Banach spaces valued functions; evolution problems for (non-linear) partial differential equations as Cauchy problems in infinite dimensional dynamical spaces. Global analysis of the longterm behavior of dissipative evolution equations: attractors.

Teaching methods

Teaching consists usually in lectures at the (possibly virtual) blackboard: there subjects are throughly developed and duly commented. Student questions and comments are welcome and encouraged. Although not mandatory, attendance is strongly recommended. The course is held in Italian. All teaching technical and practical information, as well as the teaching material, will be uploaded to the Dolly platform. The student is invited to register and consult this platform regularly. (*) due to the COVID19 health situation, the methods of delivery of the lessons could undergo changes and be carried out remotely on a platform to be indicated, however favoring the virtual synchronous mode.

Assessment methods

The student is required to present a 45 minutes talk devoted to course topics or in-depth analysis of close subjects. During the oral exam, questions on the whole course contents may be asked. The exams might be either in presence or on online, depending on the COVID19 epidemic’s evolution. The score, out of thirty, will be known at the end of the exam.
