let Al be QC-alphabet ; :: thesis: for A being non empty set
for J being interpretation of Al,A holds J |= VERUM Al
let A be non empty set ; :: thesis: for J being interpretation of Al,A holds J |= VERUM Al
let J be interpretation of Al,A; :: thesis: J |= VERUM Al
let v be Element of Valuations_in (Al,A); :: according to VALUAT_1:def 8 :: thesis: J,v |= VERUM Al
thus J,v |= VERUM Al by Th32; :: thesis: verum
