merged

all FCB lemmas

exported various FCB-lemmas to a separate file

Express trans_db with Option.map and Option.bind. Possibly mbind is a copy of bind?

Define a version of aux only for same binders. Completeness is fine.

Move If / Let with 'True' to the end of Lambda

merged

tuned

added an example that recurses over two arguments; the interesting proof-obligation is not yet done

Let with a different invariant; not true.

Add non-working Lambda_F_T using FCB2

Added non-working CPS3 using FCB2

Change CPS1 to FCB2

Did the proofs of height and subst for Let with list-like binders. Having apply_assns allows proving things by alpha_bn

side-by-side tests of lets with single assignment; deep-binder case works if the recursion is avoided using an auxiliary function

Exhaust Issue

clarified a sentence

more code refactoring

combined distributed data for alpha in alpha_result (partially done)

moved Classical and Let temporarily into a section where "sorry" is allowed; this makes all test go through

added a warning if a theorem is already declared as equivariant

merged

Prove bn injectivity and experiment more with Let

some experiments

trying new fcb in let/subst

Leftover only inj and eqvt

eapply fcb ok

Removed Inl and Inr

relaxed type in fcb

fcb with explicit bn function

added let-rec example

Experiments with res

proved the fcb also for sets (no restriction yet)

copied all work to Lambda.thy; had to derive a special version of fcb1 for concrete atom

streamlined the fcb-proof and made fcb1 a special case of fcb

completed proof in Classical; the fcb lemma works for any list of atoms (despite what was written earlier)

fcb for multible (list) binders; at the moment all of them have to have the same sort (at-class); this should also work for set binders, but not yet for restriction.

renamed ds to dset (disagreement set)

added small lemma about disagreement set

merge

New-style fcb for multiple binders.

equality of lst_binder and a few helper lemmas [l]lst. T = [l]lst. S <-> T = S

only one of the fcb precondistions are needed (probably the same with the perm-conditions)

another change to the fcb2; this is needed in order to get all proofs through in Lambda.thy

did all cases, except the multiple binder case

an alternative FCB for Abs_lst1; seems simpler but not as simple as I thought; not sure whether it generalises to multiple binders.

except for the interated binder case, finished definition in Calssical.thy

Make examples work with non-precompiled image

Remove Lambda_add.thy

The examples in Lambda_add can be defined by nominal_function directly

Theory name changes for JEdit

More usual names for substitution properties

Second Fixed Point Theorem

Speed-up the completeness proof.

the simplifier can simplify "sort (atom a)" if a is a concrete atom type declared with atom_decl

added file

expanded the example

fixed nasty bug with type variables in nominal_datatypes; this included to be careful with the output of the inductive and function package

tuned

deleted some dead code
