Unprovability and Proving Unprovability
Studia Logica 103 (3):559-578 (2015)
Abstract
We investigate the “unprovability of unprovability”. Given a sentence P and a fixed base theory T, the unprovability of P is the sentence “\ ”. We show that the unprovability of an unprovable true sentence can be “hard to prove”Other Versions
