Animated Logical Graphs • 32

Re: R.J. Lipton and K.W. ReganProof Checking

Dear Dick/Ken,

Here’s a place where I explore different shapes of proofs in a propositional calculus deriving from the graphical systems of Charles S. Peirce and G. Spencer Brown.

I don’t know whether that helps any with \mathrm{P} \overset{\underset{?}{}}{=} \mathrm{NP} but it does supply a lot of nice pictures to contemplate.
