Gödel logic is named after a mathematician with what nationality?
Gödel logic In mathematical logic, a first-order Gödel logic is a member of a family of finite- or infinite-valued logics in which the sets of truth values "V" are closed subsets of the interval [0,1] containing both 0 and 1. Different such sets "V" in general determine different Gödel logics. The concept is named after Kurt Gödel.
Löb's theorem In mathematical logic, Löb's theorem states that in any formal system F with Peano arithmetic (PA), for any formula "P", if it is provable in F that "if "P" is provable in F then "P" is true", then "P" is provable in F. More formally, if "Bew(#P)" means that the formula "P" with Gödel number #"P" is provable (from the German "beweisbar"), then
