During proofs they must not be instantiated. Lemma x + 0 = 0 + x convention: Lemma must be true for all x.

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. Isabelle provides many operations (as ml functions) that involve theorems, and some that involve theories. Chapters 4 and 5 present examples of theory construction. Specific language elements introduced by isabelle/hol are described in part iii. Although the main language elements are already provided by the isabelle/pure framework, examples given in the … 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 …
