Definition (continued)<br />

Atomic L-formulae are those which are composed<br />

according to 1., we call them At L (X) (X ⊆ VAR). The set<br />

of all L-formulae with respect to X is called F ml L (X).<br />

Positive formulae (F ml + L<br />

(X)) are those which are<br />

composed using only 1, 3. and 4.<br />

If ϕ is a L-formula and is part of an other L-formula ψ then<br />

ϕ is called sub-formula of ψ.
