WebFeb 4, 2012 · The involution property and De Morgan's law follow easily from this fact. To see the antimonotonicity property, recall that x ≤ y is equivalent to x ∨ y = y. Hence γ ( x ∨ y) = γ ( y) and, by De Morgan's law, γ ( x) ∧ γ ( y) = γ ( y) which in turn is equivalent to γ ( y) ≤ γ ( x ). View chapter Purchase book. Web1 It can be shown that De Morgan's laws hold for infinite union and infinite intersection: (1) ( ⋃ i ∈ I A i) c = ⋂ i ∈ I A i c (2) ( ⋂ i ∈ I A i) c = ⋃ i ∈ I A i c even if the index set I is uncountable. Here superscript c denotes complement w.r.t. universe U. Now consider an arbitrary expression of the form A 1 ∪ A 2 ∩ A 3 ∪ A 4 ∪... rush bros cars https://trunnellawfirm.com
