I:L->D,where L={A,∧,∨,},if I take ∧,∨, as the domain of interpretation function,that will make no sense. So,the domain of interpretation should not include the standalone "∧,∨, ",but it can bbtain the symbol in the form of wff,namely logic symbol combined with Atomic ,for instance I(A),I(A∧B).

We can derive that in extensional model,D is a set which including the studied instances,L is a set which can obtain objects, attributes,relations and logic operator ∧, ∨, .

As mentioned D = domain (a is in D). The set of objects of interest. But for the formal intensional model we don’t provide any objects as outcome, but we only provide the T/F. So, the D = domain, should be like only = {T, F} as mentioned in the next slide.
