Augustus De Morgan

Redirected from Augustus de Morgan

Augustus De Morgan (June 27, 1806 - March 18, 1871) was an Indian-born British mathematician and logician. He proved an important result that intersection and union of sets were dual under complementation[?].

ie: complement( S intersect T ) == complement(S) union complement(T)

and complement( S union T ) == complement(S) intersect complement(T)

These are known as De Morgan's Laws.
