====== Lecture plan ====== ===== Lectures ===== For each lecture, one or two lecturers will be appointed. The lecturer has the responsibility of: * Preparing a presentation of the literature for the given lecture. * Preparing a number of questions for discussion during/after the presentation. * Optional: Generating one or more exercises with solution, that illustrate and give an even better understanding of the material. * Upload the lecture slides (and possibly exercises) in Blackboard by Monday morning before the lecture. It is a main objective of the lectures to become trained in giving scientific lectures, and to have good discussions as these lead to a more thourough comprehension of the material. Although the lecturer have the responsibility of presenting the material, it is a joint responsibility for //all// attendants to prepare well by reading the literature in advance and participate actively in the discussions, preferably bringing their own questions for discussion. ===== Schedule (Subject to changes) ===== ^Week^Dates^Topic^^Literature^^Lecturers| ^ ^ ^ ^^Syllabus^Background Material^ | | 3 |18.01|**Introduction** |Course information \\ Reference group \\ Level of detail|Lemma 3.4 \\ Theorem 4.9| | Kristin Y.

Khalil, //Nonlinear Systems// Alternative 1: CU Nordics Edition, ISBN 9781784490133. The book can be bought at Akademika, Gløshaugen.\\ Alternative 2: 3rd Edition, Prentice Hall, 2002, 1995. ISBN 9780130673893. Click [[https://www.amazon.com/Nonlinear-Systems-3rd-Hassan-Khalil/dp/0130673897|here]] to purchase the book at Amazon.com. Both these editions contain the same material. The CU Nordics Edition is often less expensive than the 3rd edition.\\ (N.B.: Check the ISBN numbers to make sure that you get the correct edition. Several different editions exist, and for instance, the 2nd edition and the International edition does not contain all the material needed in this course. Also note that the book //Nonlinear Control// is a different book, and does not contain the material needed in this course.) Selected conference and journal papers, in addition to handouts, in particular in connection with Antonio Loria´s lectures. \\
