It will guide you through the first steps of isabelle programming, and also explain “tricks of the trade”. We also hope the tutorial will encourage students and researchers to play with isabelle and implement … Specific language elements introduced by isabelle/hol are described in part iii.

Isabelle provides many operations (as ml functions) that involve theorems, and some that involve theories. Chapters 4 and 5 present examples of theory construction. During proofs they must not be instantiated. Lemma x + 0 = 0 + x convention: Lemma must be true for all x. Isabelle has free (x), bound (x), and schematic (?x) variables. Only schematic variables can be …

Lemma must be true for all x. Isabelle has free (x), bound (x), and schematic (?x) variables. Only schematic variables can be … The isabelle/isar implementation manual describes isabelle implementation from a high-level perspective, documenting the major underlying concepts and in-terfaces.
