set function u on a field E has a countably additive non - negative

the o - field determined by E. If u is o - finite on Ethen this

**extension**) Every countably additive non - negative extended real valuedset function u on a field E has a countably additive non - negative

Then the function u with domain * is known as the Lebesgue

o - field £ * is known as the Lebesgue

and the measure space ( S , E * , u ) is the Lebesgue

Then the function u with domain * is known as the Lebesgue
