Introduction to linear logic

is manuscript is the lecture notes for the course of the same title I gave at the Summer school on linear logic and geometry of interaction that took place in Torino in August 2013. e aim of this course is to give a broad introduction to linear logic, covering enough ground to present many of the ideas and techniques of the field, while staying at a (hopefully) accessible level for beginners. For this reason, most technical development is carried out in the simple multiplicative fragment, with only hints at generaliza- tions. As prerequisites, some knowledge of classical sequent calculus and some knowledge of the �� -calculus is useful.
