Fuzzy logic t-norm

186 Views Asked by At

I am trying to understand fuzzy logic. I got to t-norms and trying to do some exercises on them.

Can you explain to me how to make a t-norm of the following formulas and verify if they are tautologies:

Lukasziewicz t-norm

$(A \Rightarrow B) \Rightarrow ((B \Rightarrow C) \Rightarrow (A\Rightarrow C))$

Product t-norm

$\neg\neg A\Rightarrow (((B\&A)\Rightarrow (C\&A))\Rightarrow (B\Rightarrow C))$

Gödel t-norm

$((A \Rightarrow B) \Rightarrow C) \Rightarrow (((B \Rightarrow A) \Rightarrow C)\Rightarrow C)$

I am confused how to make them in correct way. Thanks
