This course is an introduction to theorem proving with the Isabelle/HOL system. It is loosely based on the book Isabelle/HOL — A Proof Assistant for Higher-Order Logic and covers the most important definition mechanisms and proof methods. The course ends with an introduction to Isar, Isabelle's structured proof language.
