Here are two papers:
Local and global moves on planary trivalent graphs, lambda calculus and lambda-Scale (update 03.07.2012, final version, appears as arXiv:1207.0332)
which are still subject to change. Nevertheless most of what I am trying to communicate is there. I would appreciate mathematical comments.
This is an experiment, to see what happens if I make previews of papers available, like a kind of a blog of papers in the making.
