Duality in Lattices

72 Views Asked by At

I am studying Lattices using the algebraic definition i.e. A set with 2 binary operations $\wedge , \vee$ that satisfies: Commutative of $\wedge$ and $\vee$

Associativity of $\wedge $ and $\vee$

Idempotency for $\wedge$ and $\vee$

Absorption law for $\wedge $ and $\vee$

And I got a question:

Every proposition true will remains true even if we change $\wedge$ and $\vee$?

For example a Lattice is distributive if $a\wedge (b\vee c) = (a\wedge b) \vee (a \wedge c)$

Or equivalently

$a\vee (b\wedge c) = (a\vee b) \wedge (a \vee c)$
