[tlaplus] Proving INV1
Hi all, I am reading Mr. Lamport's paper The Temporal Logic of Actions . In section 5.6 of that paper, he lays out the proof rules of simple temporal logic and simple TLA. I managed to prove the validity of STL1-6 and Lattice and I have proven TLA1 and TLA2 using the previous rules, but I am stuck trying to prove INV1, which is
I /\ [N]_f => I'
I /\ [N]_f => I
where I is a predicate, N is an action, and f is a state function.
I was thinking that you need to use either TLA1 or TLA2, but I have not had much luck. If anyone could point me in the right direction, such as by letting me know which proof rules are important in proving this rule, I would be grateful.
