The course is split into two semesters. The first part is devoted to differential calculus, integration theory in two (or several) variables and function series. The second part deals with integration along curves and surfaces, Gauss and Stokes' theorems and their consequences, and an introduction to systems of differential equations. SMID students need to take only part I (first semester - 8 credits). Both semesters are mandatory for Physics students. AIMS AND CONTENT LEARNING OUTCOMES Students will become acquainted with the most important topics in several (real) variables and how they are used in practice. We only present proofs that illustrate fundamental principles and are free of technicalities. Applications to Physics and Probability are emphasised. AIMS AND LEARNING OUTCOMES At the end of the first semester, students will be able to manipulate functions of several variables and solve basic optimization problems. Moreover they will be at their ease with mean and conditional expectation. Physics students will be able to apply vector calculus: use double, triple and line integrals in applications, including Green's Theorem, Stokes' Theorem and Divergence Theorem. PREREQUISITES First year calculus (derivatives and integrals for functions of a single variable, sequences and numerical series). Vector spaces, eigevalues and eigenvectors are frequently used. TEACHING METHODS Both theory and exercises are presented by the teacher. The first semester consists of 12 weeks with four hours of theory and two hours of exercises per week. The second semester consists of 12 weeks with three hours of theory and two hours of exercises per week.

Students with SLD certification ("specific learning disabilities"), disability or other special educational needs are advised to contact the teacher at the beginning of the course to agree on teaching and examination methods that, in compliance with the teaching objectives, take account of individual learning arrangements and provide appropriate compensatory tools. ASSESSMENT METHODS The written examination consists in solving some exercises on the topics of the course. It is approved with grade at least 15/30. The oral part aims at testing the ability of problem solving and relating objects.
